This may cause noticeable behavioural improvements under certain workloads (such as compiling software with make). Thanks to Al Boldi for making me check the fork code! http://ck.kolivas.org/patches/staircase-deadline/2.6.20.7-sd-0.44.patch http://ck.kolivas.org/patches/staircase-deadline/2.6.21-rc7-sd-0.44.patch Incrementals in http://ck.kolivas.org/patches/staircase-deadline/2.6.20.7/ http://ck.kolivas.org/patches/staircase-deadline/2.6.21-rc7/ Renicing X to -10, while not essential, is preferable. See the patch just posted called 'sched: implement staircase scheduler yaf fix' for full changelog. -- -ck
