Subject[percpu_ref] 2b0d3d3e4f: reaim.jobs_per_min -18.4% regression

Greeting,

FYI, we noticed a -18.4% regression of reaim.jobs_per_min due to commit:


commit: 2b0d3d3e4fcfb19d10f9a82910b8f0f05c56ee3e ("percpu_ref: reduce memory footprint of percpu_ref in fast path")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master


in testcase: reaim
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:

runtime: 300s
nr_task: 100%
test: short
cpufreq_governor: performance
ucode: 0x5002f01

test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/

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