[PATCH 0/3] udf: Metadata partition fixes

[Alden Tondettar <alden.tondettar@gmail.com>]

This patchset (hopefully) fixes a problem with loading some
Windows-generated UDF 2.5 filesystems, and two other problems I noticed
along the way. This has only been tested on a single NetBSD-generated
image (works before, works now) and a few Windows-7-generated images
(triggered KASAN and failed to mount before, works fine now), but I don't
have any other UDF 2.5 images to test it on.

As I was getting ready to post this, I noticed on lkml that Laura Abbott has
just posted a similar fix (https://lkml.org/lkml/2016/5/18/489) for the
IS_ERR issue. However, I _think_ that fix is inadequate as iput() called
from udf_free_partition() will still dereference the error pointer in
s_mirror_fe on unmount.  If I'm wrong and that patch is fine, then let me
know if you want me to rework this to account for it.

Also, should MAINTAINERS list linux-fsdevel under UDF?
