UDF: fix UID and GID mount option ignorance
This patch fix weird behaviour of UDF mounting procedure. To get UID changed (for now) we have to type mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point and specifying two uid at once is strange a bit. So with the patch we are able to mount without additional 'uid=ignore' option. The same for GID option is done. This patch will not break current mount scheme (with two option). Btw this does fix (I hope) the following [BUG 6124] mount of UDF fs ignores UID and GID options http://bugzilla.kernel.org/show_bug.cgi?id=6124 Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Cc: Jan Kara <jack@ucw.cz> Cc: Michael <auslands-kv@gmx.de> Cc: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
