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 Changes from v2 (https://lore.kernel.org/r/20220518161859.21565-2-mkoutny@suse.com/) - rebased on mm-stable 02e34fff195d3a5f67cbb553795dc109a37d1dcf - collected acked-bys - proper Fixes: tag Changes from v1 (https://lore.kernel.org/r/20220513171811.730-1-mkoutny@suse.com/) - fixed mis-rebase in compilation fix patch, - added review, ack tags from v1, - applied feedback from v1 (Octave script in git tree), - added one more patch extracting common parts, - rebased on mm-stable bbe832b9db2e.
