Don't try it!! I have a bug in the code that is corrupting the cache
(noticed now).

I am working on a fix now.

I just noticed that kmem_cache_reap can theorically sleep in down() so
here I moved the cookie++ in do_try_to_free_pages(), it will be less
finegrined but safer... But I still have corruption so I am looking at
filemap.c now...

BTW, why kmem_cache_reap() need a serializing semaphore?
