[PATCH] MAINTAINERS: rename MM to MM MISC, add missing files

[PATCH] MAINTAINERS: rename MM to MM MISC, add missing files

[Lorenzo Stoakes]

To fit in with other sections within MAINTAINERS for memory management
files, rename the MEMORY MANAGEMENT section to MEMORY MANAGEMENT - MISC to
contain files that are not described by other sections.

We also add missing files to MEMORY MANAGEMENT - MISC and MEMORY MANAGEMENT
- CORE sections.

Move over appropriate files to the core section, and in both sections add
remaining missing files. At this point, with the other recent MAINTAINERS
changes, this should now mean that every memory management-related file has
a section and assigned maintainers/reviewers.

For the time being, we maintain catch-all mm/ and tools/mm/ entries for MM
- MISC, though in future we may wish to remove these to make it obvious
when files don't have assigned entries.

Finally, we copy across the maintainers/reviewers from MEMORY MANAGEMENT -
CORE to MEMORY MANAGEMENT - MISC, as it seems the two are sufficiently
related for this to be sensible.

Andrew - apologies, but there will likely be some small conflicts here
given other MAINTAINERS patches move stuff from the MEMORY MANAGEMENT
section too.

I kept patches separate in case one ends up having push-back we can still
have the rest putting missing files in place.

Note that we also have [0] going through the slab tree, as it seemed a more
suitable place to do that change to minimise conflicts on that front.

REVIEWERS NOTES:

This is based on discussions had in [1] both about this newly renamed
section and where David indicated he was open to maintainership of the misc
section.

I am sending un-RFC'd as, while a lot of files being moved about, it seems
relatively safe to put these files in core/misc and we can move them around
later if necessary.

Additionally, on the reviewers being added, these files are broadly files
that could have been placed in the 'core' section, so this is more or less
an administrative decision to split into two and so it seems reasonable to
maintain the same list of people.

Apologies if this is overly presumptuous, the intent here is for us to
finally reach a point (with the other patches applied) where (as far as I
can tell) every memory management-related file should now have MAINTAINERS
entries.

... together with this means the pre-existing reviewers of CORE will now get
CC'd on everything under mm/ - I'm not sure if this consequence was apparent
and wanted, so pointing that out. Myself, as long as whole mm/ is there, I'd
rather not be one of the R: purely for volume reasons. The misc files
themselves would have been fine.

Weren't a bunch of these moved to other sections already?

Hmm, I wrongly assumed it would act as a catch all for stuff not covered
elsewhere, but obviously you're right it will. OK will respin and put MM
section back just for this purpose.

Yeah this was a product of doing the patches separately.

Andrew sorted it out.

The respin should be ok for this, modulo stuff that's not merged yet (a couple
patches where I had to fixup).
