Subject: [linus:master] [mseal]  8be7258aad:
 stress-ng.pagemove.page_remaps_per_sec -4.4% regression



Hello,

kernel test robot noticed a -4.4% regression of stress-ng.pagemove.page_remaps_per_sec on:


commit: 8be7258aad44b5e25977a98db136f677fa6f4370 ("mseal: add mseal syscall")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:

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


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