McKenney [off-list ref] CommitDate: Sat, 1 Dec 2018 12:38:50 -0800 net/core/skmsg: 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. McKenney <redacted> Cc: John Fastabend <john.fastabend@gmail.com> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: "David S.
