Hi, I know the timming of this regarding the merge window is bad. I meant to send them for days… Initially I planned to send only 5/5 of the series but then I stumbled upon the other RCU related patches and I don't see a reason I shouldn't post them. I still have one patch regarding rcutorture which I hold on to until the current issues are resolved (in case you are curious: Scott made sure BH can disabled properly in atomic context on RT (while keeping this limitation to RT only builds). The current softirq implementation does not allow to disable BH in atomic context). Sebastian
