From 36bd1a8e91c66e9def12958547548aa549de9cbf Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 6 Nov 2018 19:22:23 -0800 Subject: percpu-refcount: Replace call_rcu_sched() with call_rcu() Now that call_rcu()'s callback is not invoked until after all preempt-disable regions of code have completed (in addition to explicitly marked RCU read-side critical sections), call_rcu() can be used in place of call_rcu_sched(). This commit therefore makes that change. Signed-off-by: Paul E.
