We are moving to a far more proactive model of maintainership within mm and
thus put a great deal of emphasis on sub-maintainers being active within
the community both in terms of code contributions and review.
The MGLRU has not had much activity since being added to the kernel and the
current maintainers who kindly stepped up have unfortunately not been able
to contribute a great deal to it for over a year, nor engage all that
heavily in review.
As a result, and within no negative connotations implied whatsoever, it
seems appropriate to downgrade the current maintainers to reviewers.
At this time nobody is quite exercising the maintainer role in this area of
the kernel, but there is encouraging activity from a number of people who
are trusted elsewhere in the kernel, and who have contributed relevant work
or review.
Therefore add further reviewers, and at this stage - to reflect the reality
on the ground - we will not have any sub-maintainers listed at all.
Each of the files listed are shared with other sections in MAINTAINERS, so
this doesn't reduce sub-maintainer coverage.
