[PATCH] mm: Remove final traces of deprecated kmem_cache_t.

[PATCH] mm: Remove final traces of deprecated kmem_cache_t.

[Robert P. J. Day]

  Remove the last use of kmem_cache_t and the deprecated typedef.

Signed-off-by: Robert P. J. Day <rpjday@mindspring.com>

  without looking too deeply into it, it looks like the last
references to kmem_cache_t can be removed, although there are still
going to be online web pages that refer to it, like

  http://old.kernelnewbies.org/documents/kdoc/kernel-api/r2382.html

Nope, let's leave that there for a couple of kernel cycles, give people  
to catch up.

It's fairly common for non-developers to download and build out-of-tree code from
random websites.  Let's not break their build unless we really need to.  In this
case there's little cost to us in giving the developers of that out-of-tree code
time to do an update.
