Subject: [tip:sched/urgent] [sched/eevdf] d4ac164bde: hackbench.throughput
35.8% improvement
hi, Chenyu,
this report is FYI that we observed expected performance improvement when your
commit is in tip:sched/urgent branch.
Hello,
kernel test robot noticed a 35.8% improvement of hackbench.throughput on:
commit: d4ac164bde7a12ec0a238a7ead5aa26819bbb1c1 ("sched/eevdf: Fix wakeup-preempt by checking cfs_rq->nr_running")
