Hello,
kernel test robot noticed a -90.3% regression of stress-ng.sem.ops_per_sec on:
commit: f879827b83e4d654841ce0163381f4c2604a8c73 ("sched/fair: Add trivial fair server")
https://git.kernel.org/cgit/linux/kernel/git/peterz/queue.git sched/more
testcase: stress-ng
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory
