[ANNOUNCE][RFC] PlugSched-6.5.1 for 2.6.21

[ANNOUNCE][RFC] PlugSched-6.5.1 for 2.6.21

[Peter Williams]

The main change in this version is to fix bugs introduced to SPA 
schedulers during modifications to handle a recent change to the 
scheduler driver interface to take account of recent changes to the load 
balancing code.

This patch also includes a patch to sis900 code to enable it to boot on 
my system for testing (patch supplied by Neil Horman).

A patch for 2.6.21 is available at:

<http://downloads.sourceforge.net/cpuse/plugsched-6.5.1-for-2.6.21.patch>

and a quilt/gquilt patch series is available at:

<http://downloads.sourceforge.net/cpuse/plugsched-6.5.1-for-2.6.21.patch-series.tar.gz>

Very Brief Documentation:

You can select a default scheduler at kernel build time.  If you wish to
boot with a scheduler other than the default it can be selected at boot
time by adding:

cpusched=<scheduler>

to the boot command line where <scheduler> is one of: ingosched,
ingo_ll, nicksched, staircase, spa_no_frills, spa_ws, spa_svr, spa_ebs
or zaphod.  If you don't change the default when you build the kernel
the default scheduler will be ingosched (which is the normal scheduler).

The scheduler in force on a running system can be determined by the
contents of:

/proc/scheduler

Control parameters for the scheduler can be read/set via files in:

/sys/cpusched/<scheduler>/
