There is really only one SMP bugfix - the one for handling the deadlock
case. That currently corrupts IDE disk very occasionally for a few unlucky
folks. So that won't go in until resolved.

The other possible one is the capslock patch. Ingo ?

In case you haven't heard, I now have a new version of my deadlock patch that
should be safe for IDE systems too. I now have reports from a few people of
operation under heavy load with no IDE problems nor SMP lockups. I think the
capslock patch is also included, but it wouldn't hurt for someone to check in
case there's a different patch than the allow_interrupts one I have.
