rcu: Make expedited RCU-sched grace period immediately detect idle Currently, sync_sched_exp_handler() will force a reschedule unless this CPU has already checked in or unless a reschedule has already been called for. This is clearly wasteful if sync_sched_exp_handler() interrupted an idle CPU, so this commit immediately reports the quiescent state in that case. Signed-off-by: Paul E.
