Subject: [PATCH] [3/3] sched: increase ksoftirqd priority
Date: Fri, 20 Apr 2007 01:03:51 +1000 [thread overview]
Message-ID: <200704200103.51443.kernel@kolivas.org> (raw)
More aggressive nice discrimination by the Staircase-Deadline cpu scheduler
means ksoftirqd is getting significantly less cpu than previously. Adjust
nice value accordingly for similar cpu distribution.
