Subject: [linus:master] [mm]  c0bff412e6:  stress-ng.clone.ops_per_sec -2.9%
 regression



Hello,

kernel test robot noticed a -2.9% regression of stress-ng.clone.ops_per_sec on:


commit: c0bff412e67b781d761e330ff9578aa9ed2be79e ("mm: allow anon exclusive check over hugetlb tail pages")
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: clone
	cpufreq_governor: performance




If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@...el.com>
| Closes: https://lore.kernel.org/oe-lkp/202407301049.5051dc19-oliver.sang@intel.com
