rcu: avoid pointless blocked-task warnings

Browse source

If the RCU callback-processing kthread has nothing to do, it parks in
a wait_event().  If RCU remains idle for more than two minutes, the
kernel complains about this.  This commit changes from wait_event()
to wait_event_interruptible() to prevent the kernel from complaining
just because RCU is idle.
