Subject[PATCH tip/core/rcu 16/20] rcu: Fix misprint in srcu_funnel_exp_start
Date
From: Ildar Ismagilov <devix84@gmail.com>

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.
