I don't know if anyone would find this useful but this is the Makefile I
use to generate a patch against an arbitrary kernel tree. We compile
aufs directly into the kernel rather than as a module so having the
patch is quite handy.
cheers,

# Initial checkout:
#
# $ cvs -d:pserver:[EMAIL PROTECTED]:/cvsroot/aufs login
# (CVS password is empty)
# $ cvs -z3 -d:pserver:[EMAIL PROTECTED]:/cvsroot/aufs co aufs
#
# Put this Makefile into the aufs dir.
#
# KDIR variable determines source location, otherwise uname -r is used.
#
# ie. "make KDIR=/usr/src/linux-source-2.6.24-ubuntu patch"
# to create a patch against that tree.
#
# make patch_clean to clean up after creating a patch - this is actually
# important since the existence of fs/aufs|aufs25/Kconfig is how the patch
# target knows which subtree to copy.
