McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Tue, 20 Feb 2018 16:12:27 -0800 rcu: Fix misprint in srcu_funnel_exp_start The srcu_funnel_exp_start() function checks to see if the srcu_struct structure's expedited grace period counter needs updating to reflect a newly arrived request for an expedited SRCU grace period. Unfortunately, the check is backwards, so this commit reverses the sense of the test. Signed-off-by: Ildar Ismagilov <devix84@xxxxxxxxx> Signed-off-by: Paul E.
