The attached patch changes all the filesystems in the kernel to deal with the
change to get_sb(). In most cases the responsibility is just passed on to the
convenience functions in the core kernel. In the remaining cases,
simple_set_mnt() is now called from the filesystem and/or the appropriate
type of return value is percolated back.

locking rules:

get_sb yes yes
kill_sb yes yes
-->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.
