Subject: [ANNOUNCE] sched: schedtop utility

Hi all scheduler developers,
  I had an itch to scratch w.r.t. watching the stats in /proc/schedstats, and it appears that the perl scripts referenced in Documentation/scheduler/sched-stats.txt do not support v14 from HEAD so I whipped up a little utility I call "schedtop".

This utility will process statistics from /proc/schedstat such that the busiest stats will bubble up to the top.  It can alternately be sorted by the largest stat, or by name.  Stats can be included or excluded based on reg-ex pattern matching.

You can download the tarball here:

ftp://ftp.novell.com/dev/ghaskins/schedtop.tar.gz

I have also posted it to the opensuse build service for generating RPMS for a handful of 32/64-bit x86 distros for your convenience:

http://download.opensuse.org/repositories/home:/ghaskins/

(Note that the build is still in progress for some of the favors, so if you do not see the flavor you are looking for, check back in a little while)

Comments/feedback/bug-fixes welcome!

Regards
-Greg
