Hi Andrew,

This file also contains shared logic with KSM, so we ought to put the file
in the KSM section also. I include a fix-patch to do this.

Thanks, Lorenzo

Subject: [PATCH] MAINTAINERS: also add mm_slot.h to KSM section

The mm_slot implementation is in fact common between THP and KSM so ought
to be included in both sections.

It might also be worth adding it to the KSM section since both of them
utilize it.

Good idea, will send a fix-patch to do so!

Agree, mm_slot is originally a common part extracted from THP and KSM,
and it is hoped that it can be reused by other modules in the future.
