After this patch applied the reported issue got fixed.

Great! Thank you Naresh and Michal for helping to get to the bottom of this :-)

I'll send out a new version tomorrow with the fixes applied and both of you
credited in the changelog for the detection and fix.

As we have already found that the usage around memory.{emin, elow} has
many limitations, I think memory.{emin, elow} should be used for
memcg-tree internally only, that means they can only be used to
calculate the protection of a memcg in a specified memcg-tree but
should not be exposed to other MM parts.
