Subject: [patch] [sched] SCHED_RR fix, 2.5.3-pre5
Date: Fri, 25 Jan 2002 15:23:49 +0100 (CET) [thread overview]
Message-ID: <Pine.LNX.4.33.0201251514210.7264-100000@localhost.localdomain> (raw)
the attached patch fixes sys_sched_rr_get_interval(), which returned the
timeslice value based on p->prio values, incorrectly - we calculate
timeslices based on the nice value.
