+ * DOC: B+Tree basics
+ *
+ * A B+Tree is a data structure for looking up arbitrary (currently allowing
+ * unsigned long, u32, u64 and 2 * u64) keys into pointers. The data structure
+ * is described at http://en.wikipedia.org/wiki/B-tree, we currently do not
+ * use binary search to find the key on lookups.
+ *
+ * Each B+Tree consists of a head, that contains bookkeeping information and
+ * a variable number (starting with zero) nodes. Each node contains the keys
+ * and pointers to sub-nodes, or, for leaf nodes, the keys and values for the
+ * tree entries.
+ *
+ * Each node in this implementation has the following layout:
+ * [key1, key2, ..., keyN] [val1, val2, ..., valN]
+ *
+ * Each key here is an array of unsigned longs, geo->no_longs in total. The
+ * number of keys and values (N) is geo->no_pairs.

- * Note: The alternate operations with the suffix "_nr" are used
- * to limit the range of the loop to nr_cpu_ids instead of
- * NR_CPUS when NR_CPUS > 64 for performance reasons.
- * If NR_CPUS is <= 64 then most assembler bitmask
- * operators execute faster with a constant range, so
- * the operator will continue to use NR_CPUS.
- *
- * Another consideration is that nr_cpu_ids is initialized
- * to NR_CPUS and isn't lowered until the possible cpus are
- * discovered (including any disabled cpus). So early uses
- * will span the entire range of NR_CPUS.

+/*
+ * The device-mapper userspace log module consists of a kernel component and
+ * a user-space component. The kernel component implements the API defined
+ * in dm-dirty-log.h. Its purpose is simply to pass the parameters and
+ * return values of those API functions between kernel and user-space.
+ *
+ * Below are defined the 'request_types' - DM_ULOG_CTR, DM_ULOG_DTR, etc.
+ * These request types represent the different functions in the device-mapper
+ * dirty log API. Each of these is described in more detail below.
+ *
+ * The user-space program must listen for requests from the kernel (representing
+ * the various API functions) and process them.
+ *
+ * User-space begins by setting up the communication link (error checking
+ * removed for clarity):
+ * fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
+ * addr.nl_family = AF_NETLINK;
+ * addr.nl_groups = CN_IDX_DM;
+ * addr.nl_pid = 0;
+ * r = bind(fd, (struct sockaddr *) &addr, sizeof(addr));
+ * opt = addr.nl_groups;
+ * setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP, &opt, sizeof(opt));
+ *
+ * User-space will then wait to receive requests form the kernel, which it
+ * will process as described below. The requests are received in the form,
+ * ((struct dm_ulog_request) + (additional data)). Depending on the request
+ * type, there may or may not be 'additional data'. In the descriptions below,
+ * you will see 'Payload-to-userspace' and 'Payload-to-kernel'. The
+ * 'Payload-to-userspace' is what the kernel sends in 'additional data' as
+ * necessary parameters to complete the request. The 'Payload-to-kernel' is
+ * the 'additional data' returned to the kernel that contains the necessary
+ * results of the request. The 'data_size' field in the dm_ulog_request
+ * structure denotes the availability and amount of payload data.

+ * This works in a similar way to dirents. There is a fixed size header
+ * followed by a variable length section made up of the name and the
+ * associated data. In the case of a "stuffed" entry, the value is
+ * inline directly after the name, the ea_num_ptrs entry will be
+ * zero in that case. For non-"stuffed" entries, there will be
+ * a set of pointers (aligned to 8 byte boundary) to the block(s)
+ * containing the value.
+ *
+ * The blocks containing the values and the blocks containing the
+ * extended attribute headers themselves all start with the common
+ * metadata header. Each inode, if it has extended attributes, will
+ * have either a single block containing the extended attribute headers
+ * or a single indirect block pointing to blocks containing the
+ * extended attribure headers.
+ *
+ * The maximim size of the data part of an extended attribute is 64k
+ * so the number of blocks required depends upon block size. Since the
+ * block size also determines the number of pointers in an indirect
+ * block, its a fairly complicated calculation to work out the maximum
+ * number of blocks that an inode may have relating to extended attributes.
+ *

+/**
+ * struct sx150x_platform_data - config data for SX150x driver
+ * @gpio_base: The index number of the first GPIO assigned to this
+ * GPIO expander. The expander will create a block of
+ * consecutively numbered gpios beginning at the given base,
+ * with the size of the block depending on the model of the
+ * expander chip.
+ * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
+ * instead of as an oscillator, increasing the size of the
+ * GP(I)O pool created by this expander by one. The
+ * output-only GPO pin will be added at the end of the block.
+ * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
+ * for each IO line in the expander. Setting the bit at
+ * position n will enable the pull-up for the IO at
+ * the corresponding offset. For chips with fewer than
+ * 16 IO pins, high-end bits are ignored.
+ * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
+ * resistor for each IO line in the expander. Setting the
+ * bit at position n will enable the pull-down for the IO at
+ * the corresponding offset. For chips with fewer than
+ * 16 IO pins, high-end bits are ignored.
+ * @io_open_drain_ena: A bit-mask which enables-or disables open-drain
+ * operation for each IO line in the expander. Setting the
+ * bit at position n enables open-drain operation for
+ * the IO at the corresponding offset. Clearing the bit
+ * enables regular push-pull operation for that IO.
+ * For chips with fewer than 16 IO pins, high-end bits
+ * are ignored.
+ * @io_polarity: A bit-mask which enables polarity inversion for each IO line
+ * in the expander. Setting the bit at position n inverts
+ * the polarity of that IO line, while clearing it results
+ * in normal polarity. For chips with fewer than 16 IO pins,
+ * high-end bits are ignored.
+ * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
+ * is connected, via which it reports interrupt events
+ * across all GPIO lines. This must be a real,
+ * pre-existing IRQ line.
+ * Setting this value < 0 disables the irq_chip functionality
+ * of the driver.
+ * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
+ * IRQ lines will appear. Similarly to gpio_base, the expander
+ * will create a block of irqs beginning at this number.
+ * This value is ignored if irq_summary is < 0.
+ * @reset_during_probe: If set to true, the driver will trigger a full
+ * reset of the chip at the beginning of the probe
+ * in order to place it in a known state.

+ * Platform data is used to setup the sensor chip. Meaning of the different

+ * at www.st.com web pages. Currently the platform data is used
+ * only for the 8 bit device. The 8 bit device has two wake up / free fall
+ * detection units and click detection unit. There are plenty of ways to
+ * configure the chip which makes is quite hard to explain deeper meaning of
+ * the fields here. Behaviour of the detection blocks varies heavily depending
+ * on the configuration. For example, interrupt detection block can use high
+ * pass filtered data which makes it react to the changes in the acceleration.
+ * Irq_flags can be used to enable interrupt detection on the both edges.
+ * With proper chip configuration this produces interrupt when some trigger
+ * starts and when it goes away.

+This header file (and its .c file; kernel-doc of functions see there)
+ define a helper framework to easily keep track of index:label associations,
+ and changes to an "active set" of objects, as well as pending transactions,
+ to persistently record those changes.
+
+ We use an LRU policy if it is necessary to "cool down" a region currently in
+ the active set before we can "heat" a previously unused region.
+
+ Because of this later property, it is called "lru_cache".
+ As it actually Tracks Objects in an Active SeT, we could also call it
+ toast (incidentally that is what may happen to the data on the
+ backend storage uppon next resync, if we don't get it right).
+
+What for?
+
+We replicate IO (more or less synchronously) to local and remote disk.
+
+For crash recovery after replication node failure,
+ we need to resync all regions that have been target of in-flight WRITE IO
+ (in use, or "hot", regions), as we don't know wether or not those WRITEs have
+ made it to stable storage.
+
+ To avoid a "full resync", we need to persistently track these regions.
+
+ This is known as "write intent log", and can be implemented as on-disk
+ (coarse or fine grained) bitmap, or other meta data.
+
+ To avoid the overhead of frequent extra writes to this meta data area,
+ usually the condition is softened to regions that _may_ have been target of
+ in-flight WRITE IO, e.g. by only lazily clearing the on-disk write-intent
+ bitmap, trading frequency of meta data transactions against amount of
+ (possibly unnecessary) resync traffic.
+
+ If we set a hard limit on the area that may be "hot" at any given time, we
+ limit the amount of resync traffic needed for crash recovery.
+
+For recovery after replication link failure,
+ we need to resync all blocks that have been changed on the other replica
+ in the mean time, or, if both replica have been changed independently [*],
+ all blocks that have been changed on either replica in the mean time.
+ [*] usually as a result of a cluster split-brain and insufficient protection.
+ but there are valid use cases to do this on purpose.
+
+ Tracking those blocks can be implemented as "dirty bitmap".
+ Having it fine-grained reduces the amount of resync traffic.
+ It should also be persistent, to allow for reboots (or crashes)
+ while the replication link is down.
+
+There are various possible implementations for persistently storing
+write intent log information, three of which are mentioned here.
+
+"Chunk dirtying"
+ The on-disk "dirty bitmap" may be re-used as "write-intent" bitmap as well.
+ To reduce the frequency of bitmap updates for write-intent log purposes,
+ one could dirty "chunks" (of some size) at a time of the (fine grained)
+ on-disk bitmap, while keeping the in-memory "dirty" bitmap as clean as
+ possible, flushing it to disk again when a previously "hot" (and on-disk
+ dirtied as full chunk) area "cools down" again (no IO in flight anymore,
+ and none expected in the near future either).
+
+"Explicit (coarse) write intent bitmap"
+ An other implementation could chose a (probably coarse) explicit bitmap,
+ for write-intent log purposes, additionally to the fine grained dirty bitmap.
+
+"Activity log"
+ Yet an other implementation may keep track of the hot regions, by starting
+ with an empty set, and writing down a journal of region numbers that have
+ become "hot", or have "cooled down" again.
+
+ To be able to use a ring buffer for this journal of changes to the active
+ set, we not only record the actual changes to that set, but also record the
+ not changing members of the set in a round robin fashion. To do so, we use a
+ fixed (but configurable) number of slots which we can identify by index, and
+ associate region numbers (labels) with these indices.
+ For each transaction recording a change to the active set, we record the
+ change itself (index: -old_label, +new_label), and which index is associated
+ with which label (index: current_label) within a certain sliding window that
+ is moved further over the available indices with each such transaction.
+
+ Thus, for crash recovery, if the ringbuffer is sufficiently large, we can
+ accurately reconstruct the active set.
+
+ Sufficiently large depends only on maximum number of active objects, and the
+ size of the sliding window recording "index: current_label" associations within
+ each transaction.
+
+ This is what we call the "activity log".
+
+ Currently we need one activity log transaction per single label change, which
+ does not give much benefit over the "dirty chunks of bitmap" approach, other
+ than potentially less seeks.
+
+ We plan to change the transaction format to support multiple changes per
+ transaction, which then would reduce several (disjoint, "random") updates to
+ the bitmap into one transaction to the activity log ring buffer.
+*/
+
+/* this defines an element in a tracked set
+ * .colision is for hash table lookup.
+ * When we process a new IO request, we know its sector, thus can deduce the
+ * region number (label) easily. To do the label -> object lookup without a
+ * full list walk, we use a simple hash table.
+ *
+ * .list is on one of three lists:
+ * in_use: currently in use (refcnt > 0, lc_number != LC_FREE)
+ * lru: unused but ready to be reused or recycled
+ * (ts_refcnt == 0, lc_number != LC_FREE),
+ * free: unused but ready to be recycled
+ * (ts_refcnt == 0, lc_number == LC_FREE),
+ *
+ * an element is said to be "in the active set",
+ * if either on "in_use" or "lru", i.e. lc_number != LC_FREE.
+ *
+ * DRBD currently (May 2009) only uses 61 elements on the resync lru_cache
+ * (total memory usage 2 pages), and up to 3833 elements on the act_log
+ * lru_cache, totalling ~215 kB for 64bit architechture, ~53 pages.
+ *
+ * We usually do not actually free these objects again, but only "recycle"
+ * them, as the change "index: -old_label, +LC_FREE" would need a transaction
+ * as well. Which also means that using a kmem_cache to allocate the objects
+ * from wastes some resources.
+ * But it avoids high order page allocations in kmalloc.

+ * Locking
+ * =======
+ *
+ * @lock is a softirq-safe spinlock protecting @queue as well as
+ * @cur_slot, @mrq and @state. These must always be updated
+ * at the same time while holding @lock.
+ *
+ * The @mrq field of struct dw_mci_slot is also protected by @lock,
+ * and must always be written at the same time as the slot is added to
+ * @queue.
+ *
+ * @pending_events and @completed_events are accessed using atomic bit
+ * operations, so they don't need any locking.
+ *
+ * None of the fields touched by the interrupt handler need any
+ * locking. However, ordering is important: Before EVENT_DATA_ERROR or
+ * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
+ * interrupts must be disabled and @data_status updated with a
+ * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
+ * CMDRDY interupt must be disabled and @cmd_status updated with a
+ * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
+ * bytes_xfered field of @data must be written. This is ensured by
+ * using barriers.

/**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ * these registrations are ignored until the interface type is
+ * changed again. This means that changing the interface type can
+ * lead to a situation that couldn't otherwise be produced, but
+ * any such registrations will be dormant in the sense that they
+ * will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+ * optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
+ * which channel the frame is to be transmitted or was received. If this
+ * channel is not the current channel (remain-on-channel or the

+ * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command

+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ * be lost, thus blocking readers forever.
+ * If this synchronization point is not a mutex, but a spinlock or
+ * spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ * are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ * pure reads. But if they have to fetch many values, it's better to not allow
+ * preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ * (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ * read partial values)
+ *
+ * 7) For softirq uses, readers can use u64_stats_fetch_begin_bh() and
+ * u64_stats_fetch_retry_bh() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])
+ *
+ * spin_lock_bh(...) or other synchronization to get exclusive access
+ * ...
+ * u64_stats_update_begin(&stats->syncp);
+ * stats->bytes64 += len; // non atomic operation
+ * stats->packets64++; // non atomic operation

+ * tpackets = stats->packets64; // non atomic operation
+ * } while (u64_stats_fetch_retry(&stats->syncp, start));

- * The vstusb module is a standard usb 'client' driver running on top of the
- * standard usb host controller stack.
- *
- * In general, vstusb supports standard bulk usb pipes. It supports multiple
- * devices and multiple pipes per device.
- *
- * The vstusb driver supports two interfaces:
- * 1 - ioctl SEND_PIPE/RECV_PIPE - a general bulk write/read msg
- * interface to any pipe with timeout support;
- * 2 - standard read/write with ioctl config - offers standard read/write
- * interface with ioctl configured pipes and timeouts.
- *
- * Both interfaces can be signal from other process and will abort its i/o
- * operation.
- *
- * A timeout of 0 means NO timeout. The user can still terminate the read via
- * signal.
- *
- * If using multiple threads with this driver, the user should ensure that
- * any reads, writes, or ioctls are complete before closing the device.
- * Changing read/write timeouts or pipes takes effect on next read/write.

+ *
+ * The fundamental structure for each device is the 'wiphy', of which each
+ * instance describes a physical wireless device connected to the system. Each
+ * such wiphy can have zero, one, or many virtual interfaces associated with

+ * the wireless part of the interface, normally this struct is embedded in the
+ * network interface's private data area. Drivers can optionally allow creating

+ * ability to create some the wireless device isn't useful.
+ *
+ * Each wiphy structure contains device capability information, and also has
+ * a pointer to the various operations the driver offers. The definitions and

+ * Explicit TProxy target rule
+ * ===========================
+ *
+ * This is used when the user wants to intercept a connection matching
+ * an explicit iptables rule. In this case the sockets are assumed
+ * matching in preference order:
+ *
+ * - match: if there's a fully established connection matching the
+ * _packet_ tuple, it is returned, assuming the redirection
+ * already took place and we process a packet belonging to an
+ * established connection
+ *
+ * - match: if there's a listening socket matching the redirection
+ * (e.g. on-port & on-ip of the connection), it is returned,
+ * regardless if it was bound to 0.0.0.0 or an explicit
+ * address. The reasoning is that if there's an explicit rule, it
+ * does not really matter if the listener is bound to an interface
+ * or to 0. The user already stated that he wants redirection
+ * (since he added the rule).
+ *
+ * "socket" match based redirection (no specific rule)
+ * ===================================================
+ *
+ * There are connections with dynamic endpoints (e.g. FTP data
+ * connection) that the user is unable to add explicit rules
+ * for. These are taken care of by a generic "socket" rule. It is
+ * assumed that the proxy application is trusted to open such
+ * connections without explicit iptables rule (except of course the
+ * generic 'socket' rule). In this case the following sockets are
+ * matched in preference order:
+ *
+ * - match: if there's a fully established connection matching the
+ * _packet_ tuple
+ *
+ * - match: if there's a non-zero bound listener (possibly with a
+ * non-local address) We don't accept zero-bound listeners, since
+ * then local services could intercept traffic going through the
+ * box.
+ *
+ * Please note that there's an overlap between what a TPROXY target
+ * and a socket match will match. Normally if you have both rules the
+ * "socket" match will be the first one, effectively all packets
+ * belonging to established connections going through that one.
