i'm pleased to announce release -v16 of the CFS scheduler patchset. The rolled-up CFS patch against v2.6.22-rc4, v2.6.22-rc4-mm2, v2.6.21.4 or v2.6.20.13 can be downloaded from the usual place: http://people.redhat.com/mingo/cfs-scheduler/ -v16 includes smaller fixes. Continued work on precise /proc CPU accounting of both SCHED_OTHER and RT tasks by Dmitry Adamushko and Balbir Singh. Reniced tasks should now disturb nice-0 tasks even less. Also, i have changed SCHED_BATCH back to its current mainline meaning and have added a SCHED_IDLEPRIO instead (first introduced by Con Kolivas in staircase/RSDL/SD). Changes since -v15: - more /proc CPU stats accounting improvements (Dmitry Adamushko, Balbir Singh) - fix SCHED_BATCH (reported by Con Kolivas) - update_load_fair() - use 64-bit arithmetics (Dmitry Adamushko) - fix RT->NORMAL accounting issue raised by Srivatsa Vaddagiri: have correct exec_start stamping. (Dmitry Adamushko) - check for negative deltas in task_sched_runtime() (Dmitry Adamushko) - check for large forward-jumping sched_clock() - cleanup: remove task_struct :: last_ran (Dmitry Adamushko) - /proc/sched_debug printk fixes (Andrew Morton) - add SCHED_IDLEPRIO - consolidate the granularity settings and make them scale together - improve /proc/sched_debug output - remove the yield workarounds - the default seems to be working now. - introduce lower and upper limits for the granularity tunables. Setting them to zero accidentally broke nice levels. - various small fixes/cleanups As usual, any sort of feedback, bugreport, fix and suggestion is more than welcome!
