[Devil-linux-develop] RTOS patch for DL

[Serge L. <se...@nn...>]

Dear Sirs,

 I've done a performance patch for DL 1.2.6 (2.4.31 kernel). It's
based on  Con Kolivas patches and composed of batch O(1) scheduler,
kernel preemption patch (Robert Love), low latency patch, CK
interactivity and read Latency2 patch (read into a heavy writing
system). I haven't add a Variable HZ patch yet, but I'm going to do
it. Unfortunately vhz patch and performance patch are incompatible
now. 

Also I suggest to add Con Kolivas schedtool to DL.

PS. The /etc/sysctl.conf is absent now. But for enabling low latency
we have set /proc/sys/kernel/lowlatency to "1" or delete
"CONFIG_LOLAT_SYSCTL=y" from config_linux.lowlat
