[PATCH] MAINTAINERS: add reverse mapping section
Posted by Lorenzo Stoakes 8 months ago 
Separate out the reverse mapping part of memory management and assign
appropriate maintainers and reviewers.

David has long been invovled in work with the reverse mapping and continues
to do so, so is well suited to maintain this area of the kernel.

I have a lot of experience working with the anonymous reverse mapping and
continue to work in this area, and also have good knowledge of the walking
code and code related to VMAs.

This helps people identify who to ask for help, and also additionally makes
life easier in review.

Thanks for the CC, gesture appreciated: interest yes
but capacity no, and I'm almost never an R: I'll just
keep on fixing bugs where I find them.

Absolutely, apologies I am sort of fuzzy matching cc's here based on
assuming that you guys might not be so interested these days :) obviously
more than happy to add entries if you guys have an interest! :)
