[PATCH] reiserfs: fix potential (unlikely) oops in reiserfs_get_acl
This fixes a potential oops if there is an error reported by posix_acl_from_disk(). This is mostly theoretical due to the use of magics and checksums in xattrs, but is still possible. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
