hi, Jiri Olsa, and all,

we made some investigation for this regression and confirmed the code change
in ff474a78ce is irrelevant to stress-ng performance regression, instead, it's
a code alignment issue.

if we applied below patch for both this commit and parent, the regression will
disappear.


we still make out below formal report FYI. and Feng Tang (Cced) is working on a
patch to mitigate this kind of less meaningful performance changes due to code
alignment.


Hello,

kernel test robot noticed a -12.3% regression of stress-ng.mprotect.ops_per_sec on:


commit: ff474a78cef5cb5f32be52fe25b78441327a2e7c ("uprobe: Add uretprobe syscall to speed up return probe")
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: mprotect
	cpufreq_governor: performance



Details are as below:
