Hello Dennis,
I apologize for the clutter of logs before, I'm pasting the logs of before and
after the percpu test in the case of the patchset being applied on 5.12-rc6 and
the vanilla kernel 5.12-rc6.

Hello Roman,
I've tried the v3 patch series on a POWER9 and an x86 KVM setup.
My results of the percpu_test are as follows:
Intel KVM 4CPU:4G
Vanilla 5.12-rc6
# ./percpu_test.sh
Percpu: 1952 kB
Percpu: 219648 kB
Percpu: 219648 kB
5.12-rc6 + with patchset applied
In our production experience the percpu memory allocator is sometimes struggling
with returning the memory to the system. A typical example is a creation of
several thousands memory cgroups (each has several chunks of the percpu data
used for vmstats, vmevents, ref counters etc). Deletion and
