Subject: [PATCH] sched: inaccurate calculation for normal priority
Date: Mon, 24 Nov 2008 20:05:01 +0800 [thread overview]
Message-ID: <492A986D.8030809@gmail.com> (raw)
Here we should check to see if the task is a rt ktherad or normal rt process, although right now MAX_USER_RT_PRIO is equal MAX_RT_PRIO.
