Hello,


this report is just FYI.

in the config for this test:
https://download.01.org/0day-ci/archive/20260529/202605291602.aff7d092-lkp@intel.com/config-7.1.0-rc2+
there is:
# CONFIG_PREEMPT_RT is not set


below is full report.


kernel test robot noticed a 50.7% regression of stress-ng.mutex.ops_per_sec on:


commit: dd29c017aed628076e915fe4cdfb5392fd4c5cab ("sched/rt: Have RT_PUSH_IPI be default off for non PREEMPT_RT")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git sched/core


testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 192 threads 2 sockets Intel(R) Xeon(R) 6740E  CPU @ 2.4GHz (Sierra Forest) with 256G memory
parameters:

	nr_threads: 100%
	testtime: 60s
	test: mutex
	cpufreq_governor: performance


In addition to that, the commit also has significant impact on the following tests:
