[git patch] add and use include/linux/magic.h

From: Jeff Garzik
Date: Sun Sep 24 2006 - 12:19:15 EST



Along the lines of linux/poison.h, do a similar thing with filesystem
superblock (and later perhaps, other) magic numbers. This permits
us to delete several headers which -only- included the superblock
magic number, and it integrates well with dwmw2's header_check /
header_install stuff.

Please pull from 'magic' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/misc-2.6.git magic
