Hmm... This is a really long report and quite a bit different from the previous one. I need some time for this. BTW: you sent before a lockdep report with hlist_lock problem. I think this could be fixed in some independent patch to make this all more readable. Are all the other changes in this current patch only because of this or previous lockdep report or for some other reasons (or reports) yet?
