Subject: [PATCH v2 tip/core/rcu 08/39] rcu: Pull rcu_sched_qs_mask into rcu_dynticks structure
Date: Mon, 17 Apr 2017 16:44:55 -0700 [thread overview]
Message-ID: <1492472726-3841-8-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170417234452.GB19013@linux.vnet.ibm.com>
The rcu_sched_qs_mask variable is yet another isolated per-CPU variable,
so this commit pulls it into the pre-existing rcu_dynticks per-CPU
structure.
