experimental than -rc kernels since they are generated automatically
without even a cursory glance to see if they are sane.
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.

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.

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

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.
