Subject: Re: mm: mkfs.ext4 invoked oom-killer on i386 - pagecache_get_page

My apology !
As per the test results history this problem started happening from
Bad : next-20200430 (still reproducible on next-20200519)
Good : next-20200429

The git tree / tag used for testing is from linux next-20200430 tag and reverted
following three patches and oom-killer problem fixed.

Revert "mm, memcg: avoid stale protection values when cgroup is above
protection"
Revert "mm, memcg: decouple e{low,min} state mutations from protectinn checks"
Revert "mm-memcg-decouple-elowmin-state-mutations-from-protection-checks-fix"
