# Usage: you should have the latest pull of linux-next.git
# git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
# We assume you have it on your ~/linux-next/ directory. If you do,
# just run this script from the compat-drivers directory.
# You can specify where your GIT_TREE is by doing:
#
# export GIT_TREE=/home/mcgrof/linux-next/

# given that we now need a dry run first. The algorithm
# for checking if a patch is reversed only works by
# analyzing the first hunk of a patch though so perhaps
# what we need on GNU Patch is a check for asking if
# a patch is reversed, that would not cause much
# overhead here, it would just dry run on the first
# hunk by reducing the search space considerably.
