See http://lwn.net/Articles/289013/ for more information on this topic, and
stay tuned; much is still in flux where linux-next is involved.
Besides the mmotm and linux-next trees, the kernel source tree now contains
the drivers/staging/ directory and many sub-directories for drivers or
filesystems that are on their way to being added to the kernel tree
proper, but they remain in drivers/staging/ while they still need more
work.
2.4.1: STAGING TREES
The kernel source tree now contains the drivers/staging/ directory, where
many sub-directories for drivers or filesystems that are on their way to
being added to the kernel tree live. They remain in drivers/staging while
they still need more work; once complete, they can be moved into the
kernel proper. This is a way to keep track of drivers that aren't
up to Linux kernel coding or quality standards, but people may want to use
them and track development.
Greg Kroah-Hartman currently (as of 2.6.36) maintains the staging tree.
Drivers that still need work are sent to him, with each driver having
its own subdirectory in drivers/staging/. Along with the driver source
files, a TODO file should be present in the directory as well. The TODO
file lists the pending work that the driver needs for acceptance into
the kernel proper, as well as a list of people that should be Cc'd for any
patches to the driver. Staging drivers that don't currently build should
have their config entries depend upon CONFIG_BROKEN. Once they can
be successfully built without outside patches, CONFIG_BROKEN can be removed.
