Subject: [PATCH 00/22] sched: Reduce runqueue lock contention -v5
Date: Wed, 02 Mar 2011 18:38:31 +0100 [thread overview]
Message-ID: <20110302173831.295031866@chello.nl> (raw)
This patch series aims to optimize remote wakeups by moving most of the
work of the wakeup to the remote cpu and avoid bouncing runqueue data
structures where possible.
If there are no more 'fun' bits left I'll queue this work for .40.
