All of the new 2.6.18 stuff already has been in there, this is a bit too late for it. I have no problem with taking this and letting it get beat on for a few months and then go into 2.6.19. > So the question is - are we brave/confident enough to try to stabilize > this in the next couple of days and drop it into 2.6.18 together with > the other bits of genirq?

Hm? I don't object to genirq to go in now for 2.6.18, but this series is too new.
