Subject: [patch] mm/memcontrol.c::mem_cgroup_migrate() - replace another local_irq_disable() w. local_lock_irq()
Date: Sun, 05 Jun 2016 08:11:13 +0200 [thread overview]
Message-ID: <1465107073.4263.3.camel@gmail.com> (raw)
In-Reply-To: <20160603104424.GA18975@linutronix.de>
v4.6 grew a local_irq_disable() in mm/memcontrol.c::mem_cgroup_migrate().
Convert it to use the existing local lock (event_lock) like the others.
