Document things that I would've liked to have known when submitting a driver
to gregkh for staging.

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.
