File reiserfs-unaligned.diff of Package reiserfs
From: Jeff Mahoney <jeffm@suse.com> Subject: [PATCH] reiserfsprogs: remove dependency on asm/unaligned.h We probably shouldn't have ever been including asm/unaligned.h, though I think I'm the one who added it there in the first place. This patch borrows the unaligned accessor functions from the 3.6.20 code.
