->read_inode() is not a method - it's a callback used in iget().
rules for mount_sem are not too nice - it is going to die and be replaced
by better scheme anyway.
->remount_fs() will have the s_umount lock if it's already mounted.
When called from get_sb_single, it does NOT have the s_umount lock.
