6   <code class="function">generic_shutdown_super</code> does all fs-independent work on superblock
7   shutdown.  Typical -&gt;<code class="function">kill_sb</code> should pick all fs-specific objects
8   that need destruction out of superblock, call <code class="function">generic_shutdown_super</code>
9   and release aforementioned objects.  Note: dentries and inodes _are_
10   taken care of and do not need specific handling.
11   </p><p>

13   Upon calling this function, the filesystem may no longer alter or
14   rearrange the set of dentries belonging to this super_block, nor may it
15   change the attachments of dentries to inodes.
