From a5d6d3a1b00a0ad88f07c3a727c79b27915278e3 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 16 Apr 2014 09:06:24 -0700 Subject: [PATCH] softirq: A single rcu_bh_qs() call per softirq set is enough Calling rcu_bh_qs() after every softirq action is not really needed. What RCU needs is at least one rcu_bh_qs() per softirq round to note a quiescent state was passed for rcu_bh. Note for Paul and myself : this could be inlined as a single instruction and avoid smp_processor_id() (sone this_cpu_write(rcu_bh_data.passed_quiesce, 1)) Signed-off-by: Eric Dumazet Signed-off-by: Paul E.
