The patch against v2.6.21-rc7 can be downloaded from: http://redhat.com/~mingo/cfs-scheduler/ this CFS release too is mainly about fixing regressions and improving interactivity, so the rate of change is relatively low: 11 files changed, 136 insertions(+), 72 deletions(-) in particular the preemption fix could resolve the 'desktop slows down under IO load' reports and the 'firefox does not switch tabs fast enough' reports as well. The suspend2 crash and the yield related Kaffeine hangs should be resolved as well. Changes since -v3: - usability fix: automatic renicing of kernel threads such as keventd, OOM tasks and tasks doing privileged hardware access (such as Xorg). (This is a substitute for group scheduling until the group scheduling details have been worked out.) - bugfix: buggy yield() caused suspend2 problems - preemption fix: it caused desktop app latencies As usual, any sort of feedback, bugreport, fix and suggestion is more than welcome, Ingo
