experimental than -rc kernels since they are generated automatically

-2.6.x -mm kernel patches
-------------------------
-These are experimental kernel patches released by Andrew Morton. Andrew
-takes all of the different subsystem kernel trees and patches and mushes
-them together, along with a lot of patches that have been plucked from
-the linux-kernel mailing list. This tree serves as a proving ground for
-new features and patches. Once a patch has proved its worth in -mm for
-a while Andrew or the subsystem maintainer pushes it on to Linus for
-inclusion in mainline.
-
-It is heavily encouraged that all new patches get tested in the -mm tree
-before they are sent to Linus for inclusion in the main kernel tree. Code
-which does not make an appearance in -mm before the opening of the merge
-window will prove hard to merge into the mainline.
-
-These kernels are not appropriate for use on systems that are supposed
-to be stable and they are more risky to run than any of the other
-branches.
-
-If you wish to help out with the kernel development process, please test
-and use these kernel releases and provide feedback to the linux-kernel
-mailing list if you have any problems, and if everything works properly.
-
-In addition to all the other experimental patches, these kernels usually
-also contain any changes in the mainline -git kernels available at the
-time of release.
-
-The -mm kernels are not released on a fixed schedule, but usually a few
--mm kernels are released in between each -rc kernel (1 to 3 is common).

Subsystem Specific kernel trees and patches
-------------------------------------------
-A number of the different kernel subsystem developers expose their
-development trees so that others can see what is happening in the
-different areas of the kernel. These trees are pulled into the -mm
-kernel releases as described above.
+The maintainers of the various kernel subsystems --- and also many
+kernel subsystem developers --- expose their current state of
+development in source repositories. That way, others can see what is
+happening in the different areas of the kernel. In areas where
+development is rapid, a developer may be asked to base his submissions
+onto such a subsystem kernel tree so that conflicts between the
+submission and other already ongoing work are avoided.
-Here is a list of some of the different kernel trees available:
- git trees:
- - Kbuild development tree, Sam Ravnborg <sam@ravnborg.org>
- git.kernel.org:/pub/scm/linux/kernel/git/sam/kbuild.git
+Most of these repositories are git trees, but there are also other SCMs
+in use, or patch queues being published as quilt series. Addresses of
+these subsystem repositories are listed in the MAINTAINERS file. Many
+of them can be browsed at http://git.kernel.org/.
- - ACPI development tree, Len Brown <len.brown@intel.com>
- git.kernel.org:/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git
+Before a proposed patch is committed to such a subsystem tree, it is
+subject to review which primarily happens on mailing lists (see the
+respective section below). For several kernel subsystems, this review
+process is tracked with the tool patchwork. Patchwork offers a web
+interface which shows patch postings, any comments on a patch or
+revisions to it, and maintainers can mark patches as under review,
+accepted, or rejected. Most of these patchwork sites are listed at
+http://patchwork.kernel.org/ or http://patchwork.ozlabs.org/.
- - Block development tree, Jens Axboe <jens.axboe@oracle.com>
- git.kernel.org:/pub/scm/linux/kernel/git/axboe/linux-2.6-block.git
+2.6.x -next kernel tree for integration tests
+---------------------------------------------
+Before updates from subsystem trees are merged into the mainline 2.6.x
+tree, they need to be integration-tested. For this purpose, a special
+testing repository exists into which virtually all subsystem trees are
+pulled on an almost daily basis:
+ http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git
+ http://linux.f-seidel.de/linux-next/pmwiki/
- - DRM development tree, Dave Airlie <airlied@linux.ie>
- git.kernel.org:/pub/scm/linux/kernel/git/airlied/drm-2.6.git
+This way, the -next kernel gives a summary outlook onto what will be
+expected to go into the mainline kernel at the next merge period.
+Adventurous testers are very welcome to runtime-test the -next kernel.

config UEVENT_HELPER_PATH
string "path to uevent helper"
depends on HOTPLUG
- default "/sbin/hotplug"
+ default ""
help
Path to uevent helper program forked by the kernel for
every uevent.
+ Before the switch to the netlink-based uevent source, this was
+ used to hook hotplug scripts into kernel device events. It
+ usually pointed to a shell script at /sbin/hotplug.
+ This should not be used today, because usual systems create
+ many events at bootup or device discovery in a very short time
+ frame. One forked process per event can create so many processes
+ that it creates a high system load, or on smaller systems
+ it is known to create out-of-memory situations during bootup.
config DEVTMPFS
- bool "Create a kernel maintained /dev tmpfs (EXPERIMENTAL)"
+ bool "Maintain a devtmpfs filesystem to mount at /dev"
depends on HOTPLUG && SHMEM && TMPFS
help
- This creates a tmpfs filesystem, and mounts it at bootup
- and mounts it at /dev. The kernel driver core creates device
- nodes for all registered devices in that filesystem. All device
- nodes are owned by root and have the default mode of 0600.
- Userspace can add and delete the nodes as needed. This is
- intended to simplify bootup, and make it possible to delay
- the initial coldplug at bootup done by udev in userspace.
- It should also provide a simpler way for rescue systems
- to bring up a kernel with dynamic major/minor numbers.
- Meaningful symlinks, permissions and device ownership must
- still be handled by userspace.
- If unsure, say N here.
+ This creates a tmpfs filesystem instance early at bootup.
+ In this filesystem, the kernel driver core maintains device
+ nodes with their default names and permissions for all
+ registered devices with an assigned major/minor number.
+ Userspace can modify the filesystem content as needed, add
+ symlinks, and apply needed permissions.
+ It provides a fully functional /dev directory, where usually
+ udev runs on top, managing permissions and adding meaningful
+ symlinks.
+ In very limited environments, it may provide a sufficient
+ functional /dev without any further help. It also allows simple
+ rescue systems, and reliably handles dynamic major/minor numbers.
config DEVTMPFS_MOUNT
- bool "Automount devtmpfs at /dev"
+ bool "Automount devtmpfs at /dev, after the kernel mounted the rootfs"
depends on DEVTMPFS
help
- This will mount devtmpfs at /dev if the kernel mounts the root
- filesystem. It will not affect initramfs based mounting.
- If unsure, say N here.
+ This will instruct the kernel to automatically mount the
+ devtmpfs filesystem at /dev, directly after the kernel has
+ mounted the root filesystem. The behavior can be overridden
+ with the commandline parameter: devtmpfs.mount=0|1.
+ This option does not affect initramfs based booting, here
+ the devtmpfs filesystem always needs to be mounted manually
+ after the roots is mounted.
+ With this option enabled, it allows to bring up a system in
+ rescue mode with init=/bin/sh, even when the /dev directory
+ on the rootfs is completely empty.
