Subject: [PATCH 0/4] memcontrol selftests fixups
Date: Wed, 18 May 2022 17:40:33 +0200	[thread overview]
Message-ID: <20220518154037.18819-1-mkoutny@suse.com> (raw)

Hello.

I'm just flushing the simple patches to make memcontrol selftests check the
events behavior we had consensus about (test_memcg_low fails). (I've dropped to
goto macros for now.)

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

The only bigger change is adjustment of the protected values to make tests
succeed with the given tolerance.

It's based on mm-stable [1] commit e240ac52f7da. AFAIC, the fixup and partial
reverts may be folded into respective commits.
Let me know if it should be (re)based on something else.

Thanks,
Michal
