Acrypto hacking.


I've done several updates for new acrypto release.
It includes per-device crypto_route memory pool, various kmap* transformation. Also started speedup work which aims in crypto_lb thread removal. This thread is used to serialize session callback calling and session removal, but this can be easily done directly from complete_session() call. It still has some slab corruption bug which must be resolved before release.
Ok, it looks like I've found where the bug lives. I think about it's resolution while going home and have created a very nice idea about high-performance priority queues in acrypto. What it currently has is a total crap actually, so I will create priority queues with O(1) session selection and doing the same will fix current slab corruption problem. It should also increase performance a little.

If things will go like I want, I plan to release new acrypto version at the end of this week or just after weekend. I do hope I will find time to test IPsec and dm-crypt from 2.6.15 git tree with new acrypto before New Year's holidays. I will be in Saint-Petersburg until Jan 2.
