<code class="function">generic_shutdown_super</code> does all fs-independent work on superblock
shutdown. Typical -><code class="function">kill_sb</code> should pick all fs-specific objects
that need destruction out of superblock, call <code class="function">generic_shutdown_super</code>
and release aforementioned objects. Note: dentries and inodes _are_
taken care of and do not need specific handling.
</p><p>
Upon calling this function, the filesystem may no longer alter or
rearrange the set of dentries belonging to this super_block, nor may it
change the attachments of dentries to inodes.
