Extract the common code to remove a dentry from the lru into a new function
dentry_lru_remove().
Two call sites used list_del() instead of list_del_init(). AFAIK the
performance of both is the same. dentry_lru_remove() does a list_del_init().
As a result dentry->d_lru is now always empty when a d
In order to support defragmentation on the dentry cache we need to have
an determined object state at all times. Without a destructor the object
would have a random state after allocation.
So provide a constructor.

Defragmentation support for buffer heads. We convert the references to
buffers to struct page references and try to remove the buffers from
those pages. If the pages are dirty then trigger writeout so that the
buffer heads can be removed later.

This implements the ability to remove inodes in a particular slab
from inode cache. In order to remove an inode we may have to write out
the pages of an inode, the inode itself and remove the dentries referring
to the node.

Slabs that are reclaimable fit the definition of the objects in

on platforms where there is no HIGHMEM. Hopefully that restriction
will vanish at some point).
