Scheduler statistics patch
Description:
This patch against 2.5.59 provides a means for collecting statistics about decisions the scheduler is making. While this initial implementation collects information across three different scheduling routines, it is easily extensible to gather information about other aspects of the scheduler if desired.
Developer:
Rick Lindsley
Status:
Submitted to project

Notes:
The patch utilizes per-cpu, cache-aligned data structures to minimize the impact to the scheduling algorithm itself. A web page further describing the patch and sample utilities that utilize it can be found at http://eaglet.rain.com/rick/linux/schedstat/index.html.
