[PATCH 0/7 v4] rcu: Fix some rcu uses in extended quiescent state
From: Frederic Weisbecker
Date: Mon Sep 26 2011 - 06:19:24 EST
Hi Paul,
Two fixes added in that set, the first two patches:
- The check on uses under extended quiescent states was buggy
- One more illegal use of RCU fixed, from inside tick_nohz_stop_sched_tick()
It has survived one day and one night of rcutorture in x86-64
with periodic cpu hotplug onlining/offlining...
No test in powerpc yet though... So I don't know yet why
you got an rcutorture failure.
Frederic Weisbecker (7):
rcu: Fix preempt-unsafe debug check of rcu extended quiescent state
rcu: Fix early call to rcu_enter_nohz() on tick stopping
nohz: Separate out irq exit and idle loop dyntick logic
nohz: Allow rcu extended quiescent state handling seperately from
tick stop
x86: Enter rcu extended qs after idle notifier call
x86: Call idle notifier after irq_enter()
rcu: Fix early call to rcu_irq_exit()
