If I hear that parking is free on weekdays and on paid on weekends, I expect it to be a scam. Uwe, the patch reverts a change which was needed for !RT + threadirqs. The commit message claims that since the referenced commit "… interrupt handlers always run with interrupts disabled on non-RT… ". This has nothing to do with _this_ change. It argues why the workaround is not needed. If the referenced commit breaks RT then this is another story. > So when you said that on on-RT the reason why it used to need a > workaround is gone made me wonder what that implies for RT. There was never reason (or a lockdep splat) for it on RT. If so you should have seen it, right? Sebastian
