The patch titled
sched: dont renice kernel threads
has been removed from the -mm tree. Its filename was
sched-dont-renice-kernel-threads.patch
This patch was dropped because I need to clear the decks
------------------------------------------------------
Subject: sched: dont renice kernel threads
From: Con Kolivas <kernel@xxxxxxxxxxx>
The practice of renicing kernel threads to negative nice values is of
questionable benefit at best, and at worst leads to larger latencies when
kernel threads are busy on behalf of other tasks.
