locking rules:

->get_sb() returns error or a locked superblock (exclusive on ->s_umount).
->get_sb() returns error or 0 with locked superblock attached to the vfsmount
(exclusive on ->s_umount).
->kill_sb() takes a write-locked superblock, does all shutdown work on it,
unlocks and drops the reference.
