[RFC PATCH] MAINTAINERS: add mm reclaim section

[RFC PATCH] MAINTAINERS: add mm reclaim section

[Lorenzo Stoakes]

In furtherance of ongoing efforts to ensure people are aware of who
de-facto maintains/has an interest in specific parts of mm, as well trying
to avoid get_maintainers.pl listing only Andrew and the mailing list for mm
files - establish a reclaim memory management section and add relevant
maintainers/reviewers.

This is a key part of memory management so sensibly deserves its own
section.

This encompasses both 'classical' reclaim and MGLRU and thus reflects this
in the reviewers from both, as well as those who have contributed
specifically on the memcg side of things.

Seems fine to me, though I would put Johannes as M (if he is fine with
it).

Do we have plan to add mm PGTABLE section (at least should
contain mm/pgtable-generic.c, include/linux/pgtable.h, etc)?

I'm not sure which section, RECLAIM or PGTABLE, is more
appropriate for mm/pt_reclaim.c to be included in, but either of
them is fine for me.

Thanks, absolutely support this :) Will switch you out for an M when I un-RFC.

Sorry I thought I had already replied to this! :P

I think for now better to keep it in reclaim as we have a bunch of page
table code distributed over the place, which we probably need to address
separately!
