Make sure all dentries refs are released before calling kill_anon_super() so that the assumption that generic_shutdown_super() can completely destroy the dentry tree for there will be no external references holds true. What was being done in the put_super() superblock op, is now done in the kill_sb() filesystem op instead, prior to calling kill_anon_super(). The call to shrink_dcache_sb() is removed as it is redundant since shrink_dcache_for_umount() will now be called after the cleanup routine.
