Subject: [PATCH 01/14] sched/core: Fix preempt_schedule() interrupt return comment
Date: Mon, 11 Mar 2019 22:47:39 +0000	[thread overview]
Message-ID: <20190311224752.8337-2-valentin.schneider@arm.com> (raw)
In-Reply-To: <20190311224752.8337-1-valentin.schneider@arm.com>

preempt_schedule_irq() is the one that should be called on return from
interrupt, clean up the comment to avoid any ambiguity.
