Subject: [PATCH v2 5/9] sched: Add WF_TTWU, WF_EXEC wakeup flags
Date: Wed, 11 Mar 2020 18:15:57 +0000 [thread overview]
Message-ID: <20200311181601.18314-6-valentin.schneider@arm.com> (raw)
In-Reply-To: <20200311181601.18314-1-valentin.schneider@arm.com>
To remove the sd_flag parameter of select_task_rq(), we need another way of
encoding wakeup kinds. There already is a WF_FORK flag, add the missing
ones.
