Subject: Re: [PATCH 0/4] memcontrol selftests fixups

Apologies for spam due to botched sending.
Please disregard this (old) series.
The replacement should come in

https://lore.kernel.org/r/20220518161859.21565-1-mkoutny@suse.com

(That one is also not 100% correct, it's missing a Subject: therefore
may not be pass through some filters.)

The 1st patch of that v2 series is at
https://lore.kernel.org/r/20220518161859.21565-2-mkoutny@suse.com/

And I copy the cover letter here to be sure (and not to spam even more).

Subject: [PATCH v2 0/5] memcontrol selftests fixups

Hello.

I'm just flushing the patches to make memcontrol selftests check the
events behavior we had consensus about (test_memcg_low fails).

(test_memcg_reclaim, test_memcg_swap_max fail for me now but it's present
even before the refactoring.)

The two bigger changes are:
- adjustment of the protected values to make tests succeed with the given
  tolerance,
- both test_memcg_low and test_memcg_min check protection of memory in
  populated cgroups (actually as per Documentation/admin-guide/cgroup-v2.rst
  memory.min should not apply to empty cgroups, which is not the case
  currently. Therefore I unified tests with the populated case in order to to
  bring more broken tests).


Thanks,
Michal
