Sure - we can reasonably rebase portions of that stack of commits: earth4:~/tip> gll linus..core/rcu 7256cf0: rcu: Add diagnostic check for a possible CPU-hotplug race 04b0625: rcu: Fix RCU & CPU hotplug hang 7fe616c: rcu: Simplify RCU CPU-hotplug notification 240ebbf: rcu: Add synchronize_sched_expedited() rcutorture doc + updates 0acc512: rcu: Add synchronize_sched_expedited() torture tests 03b042b: rcu: Add synchronize_sched_expedited() primitive c17ef45: rcu: Remove Classic RCU Please mention the magic words "please reset core/rcu to 240ebbf before applying these patches" in the mail to me, should i forget in the days to come. (hm, what was i supposed to not forget? Weird.) Ingo
