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?
