Subject: [PATCH RESEND 1/7] sched/core: Fix preempt_schedule() interrupt return comment
Date: Tue, 28 May 2019 11:48:42 +0100	[thread overview]
Message-ID: <20190528104848.13160-2-valentin.schneider@arm.com> (raw)
In-Reply-To: <20190528104848.13160-1-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.
