Linus Torvalds1da177e2005-04-16 15:20:36 -07001The following is a list of files and features that are going to be
2removed in the kernel source tree. Every entry should contain what
3exactly is going away, why it is happening, and who is going to be doing
4the work. When the feature is removed from the kernel, it should also
5be removed from this file.

9What: devfs
10When: July 2005
11Files: fs/devfs/*, include/linux/devfs_fs*.h and assorted devfs
12 function calls throughout the kernel tree
13Why: It has been unmaintained for a number of years, has unfixable
14 races, contains a naming policy within the kernel that is
15 against the LSB, and can be replaced by using udev.

Adrian Bunk98e7f292005-06-25 14:59:37 -070020What: RAW driver (CONFIG_RAW_DRIVER)
21When: December 2005
22Why: declared obsolete since kernel 2.6.3
23 O_DIRECT can be used instead

Paul E. McKenney66cf8f12005-05-01 08:59:03 -070028What: RCU API moves to EXPORT_SYMBOL_GPL
29When: April 2006
30Files: include/linux/rcupdate.h, kernel/rcupdate.c
31Why: Outside of Linux, the only implementations of anything even
32 vaguely resembling RCU that I am aware of are in DYNIX/ptx,
33 VM/XA, Tornado, and K42. I do not expect anyone to port binary
34 drivers or kernel modules from any of these, since the first two
35 are owned by IBM and the last two are open-source research OSes.
36 So these will move to GPL after a grace period to allow
37 people, who might be using implementations that I am not aware
38 of, to adjust to this upcoming change.

43What: IEEE1394 Audio and Music Data Transmission Protocol driver,
44 Connection Management Procedures driver
45When: November 2005
46Files: drivers/ieee1394/{amdtp,cmp}*
47Why: These are incomplete, have never worked, and are better implemented
48 in userland via raw1394 (see http://freebob.sourceforge.net/ for
49 example.)
50Who: Jody McIntyre <scjody@steamballoon.com>
51
52---------------------------
53
54What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
55When: November 2005
56Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
57 more efficient. You should really be using libraw1394 for raw1394
58 access anyway.

61---------------------------
62
63What: i2c sysfs name change: in1_ref, vid deprecated in favour of cpu0_vid
64When: November 2005
65Files: drivers/i2c/chips/adm1025.c, drivers/i2c/chips/adm1026.c
66Why: Match the other drivers' name for the same function, duplicate names
67 will be available until removal of old names.

72What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
73When: November 2005
74Files: drivers/pcmcia/: pcmcia_ioctl.c
75Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a
76 normal hotpluggable bus, and with it using the default kernel
77 infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA
78 control ioctl needed by cardmgr and cardctl from pcmcia-cs is
79 unnecessary, and makes further cleanups and integration of the
80 PCMCIA subsystem into the Linux kernel device driver model more
81 difficult. The features provided by cardmgr and cardctl are either
82 handled by the kernel itself now or are available in the new
83 pcmciautils package available at
84 http://kernel.org/pub/linux/utils/kernel/pcmcia/

87---------------------------
88
89What: ip_queue and ip6_queue (old ipv4-only and ipv6-only netfilter queue)
90When: December 2005
91Why: This interface has been obsoleted by the new layer3-independent
92 "nfnetlink_queue". The Kernel interface is compatible, so the old
93 ip[6]tables "QUEUE" targets still work and will transparently handle
94 all packets into nfnetlink queue number 0. Userspace users will have
95 to link against API-compatible library on top of libnfnetlink_queue
96 instead of the current 'libipq'.
