Indeed, and I hope it gets merged, giving people the chance to test out different schedulers easily, without having to do patching, de-patching, re-patching and blah blah blah. But somehow I doubt it'll get merged now. My bet is that it won't even be taken into consideration, for the same reasons that ultimately drove Con Kolivas to giving up on development of SD. And if it's so, chances are people will get tired of trying to get it merged. :/ >> A patch for 2.6.22 is available at: >> >> >> >> Very Brief Documentation: >> >> You can select a default scheduler at kernel build time.

If I read the announcement correctly, those are the ones referred to as 'ingosched' and 'staircase' :) -- Giuseppe "Oblomov" Bilotta
