[ Merge note: this is admittedly a bit late in the cycle, and the regression is old, but the performance impact is substantial for the affected workloads so I didn't want to delay this fix. ] Thanks, Ingo ------------------> Dietmar Eggemann (1): Revert "sched/core: Reduce cost of sched_move_task when config autogroup" kernel/sched/core.c | 21 +++------------------ 1 file changed, 3 insertions(+), 18 deletions(-)
