Subject[patch] BFS 421: a couple of cleanup cases
From
Hi all

This is the first patch, namely cleanup, for 421.

I read messages says,

Interactivity: I have a usual work to be done. Loading & using Firefox with
many open tabs, downloading encoded video files, decoding them to shmfs/tmpfs
what is only partially backed by RAM (2GB RAM/ 4GB swap) and cutting,
watching them, office work in libreoffice, seldom DVD burning. In the
background there's always running an instance from worldcommunitygrid,
scheduled as SCHED_IDLE with Con Colivas's schedtool.

yeah, many things for 421 on Tualatin, and I am really glad.

And I want to do/see works,
1, cleanup with s/cpus_xyz/cpumask_xyz/g
2, remove ISO (what advantages for designing/tuning scheduler?)
3, method to measure the temperature of global runqueue lock
4, method to measure the cache affinity for given workload
[please feel free to add your ideas]

in the near future.

Messages welcome:)
