Subject: [PATCH] sched: Remove useless settings when 'tg == d->tg'
Date: Fri, 14 Aug 2020 19:12:52 +0800 [thread overview]
Message-ID: <20200814111252.36379-1-tian.xianting@h3c.com> (raw)
if 'tg == d->tg' is true, the previous settings for period,runtime
are unnecessary. So move the settings to the 'else' branch.
