[PATCH 0/4] rcu: Detect rcu uses under extended quiescent state, and fix some

From: Frederic Weisbecker
Date: Sun Jun 05 2011 - 23:11:15 EST


I found two examples with the last two patches but I suspect there are more bugs
waiting to be detected under other configs or archs.

Frederic Weisbecker (4):
rcu: Detect uses of rcu read side in extended quiescent states
nohz: Split extended quiescent state handling from nohz switch
x86: Don't call idle notifier inside rcu extended QS
x86: Call idle_exit() after irq_enter()
