+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.
+
+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/.
+
+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/.
+
+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/
+
+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.
 
-  Other kernel trees can be found listed at http://git.kernel.org/ and in
-  the MAINTAINERS file.

 	  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 "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.
