Ok, first off, very sorry for the delay. So I looked this patch over, and it looks relativly sane :) But due to the other changes Dave (and possibly you) have made to the usb tree, this patch, and the other reset one, doesn't apply anymore. I could go back and apply it to an older kernel and merge it forward, but it looks like a portion of where you want to put locks has radically changed, and I'll probably get it wrong. So, I'll hold off on applying any more usb core changes from anyone else, if you want to remerge this against the latest bk tree, and send them to me again. Again, sorry for the delay. greg k-h ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
