Here is a more complete (and hopefully accurate) reporting of the 3 patches. A) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch degrades volanomark, specjbb and specsdet B) *** test5 + sched-balance-fix-2.6.0-test3-mm3-A0.patch improves specjbb with no real change on sdet or volanomark C) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch + sched-balance-fix-2.6.0-test3-mm3-A0.patch degrades volanomark and sdet, more degrade than improvement on specjbb D) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch + sched-balance-fix-2.6.0-test3-mm3-A0.patch + sched-2.6.0-test2-mm2-A3.patch degrades volanomark and sdet, mixed results on specjbb Below are the details for each of the runs.
