Pull userns fixes from Eric Biederman:
 "This contains two small but significant fixes to fs/namespace.c.

  The first adds a filesystem refcount drop on error.  The second
  corrects a test in fs_fully_visible which could be abused to allow
  mounting of proc or sysfs, when that should not be allowed.

  To keep myself honest I have tested to ensure the incorrect test in
  fs_fully_visible actually allows improper mounting of proc before the
  fix and that when fixed the improper mounting is not allowed"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
  mnt: fs_fully_visible test the proper mount for MNT_LOCKED
  mnt: If fs_fully_visible fails call put_filesystem.
