Subject: [PATCH] sched: fix the wrong time slice value for SCHED_FIFO tasks
Date: Fri, 07 Mar 2008 09:35:06 +0800	[thread overview]
Message-ID: <47D09BCA.9050504@cn.fujitsu.com> (raw)

Function sys_sched_rr_get_interval returns wrong time slice value for
SCHED_FIFO tasks. The time slice for SCHED_FIFO tasks should be 0.
