Merge branch 'urgent.2014.06.23a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/urgent
Pull RCU fixes from Paul E. McKenney:
" This series includes the following:
1. Export a pair of debug-object interfaces for RCU that will
allow the slab allocators to avoid a recursion bug located
by Sasha Levin. Strictly speaking, this is not a regression,
but it would be good to enable the fix.
2. Address a serious performance regression on an open/close
micro-benchmark located by Dave Hansen. The offending commit
is ac1bea85781e (Make cond_resched() report RCU quiescent states). "
