Greeting, FYI, we noticed a -25.2% regression of stress-ng.sock.ops_per_sec due to commit: commit: 5f94d1b650d14e01f383e3d02e40c13a9ccecaf4 ("[PATCH] sched/fair: don't use waker's cpu if the waker of sync wake-up is interrupt") url: https://github.com/0day-ci/linux/commits/Barry-Song/sched-fair-don-t-use-wa… base: https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git
