[PATCH 0/3] MAINTAINERS: rework MEMORY MANAGEMENT - MEMORY POLICY AND MIGRATION

[David Hildenbrand (Arm)]

Let's rework MEMORY MANAGEMENT - MEMORY POLICY AND MIGRATION.

As I can use some maintenance help in that area, add Gregory as
a new co-maintainer for the split out MEMORY MANAGEMENT - NUMA PLACEMENT
section.

[PATCH 1/3] MAINTAINERS: split up MEMORY MANAGEMENT - MEMORY POLICY AND MIGRATION

[David Hildenbrand (Arm)]

Let's split it up into MIGRATION and NUMA PLACEMENT. The latter is a
better fitting description for mempolicy.c.

Make a best guess about which pieces existing reviewers are interested
in. Move the split sections to keep alphabetical order.

[PATCH 2/3] MAINTAINERS: move memory tiering under MEMORY MANAGEMENT - NUMA PLACEMENT

[David Hildenbrand (Arm)]

NUMA PLACEMENT is a better place for memory tiering.

My best guess is that existing MISC reviewers are not that interested in
memory tiering, so don't carry any over.

So you are finding a better placement for the placement bit of mm? :P

I think misc by its very definition is a place to stash stuff that doesn't
belong elsewhere so seems rasonable :P

Makes sense to me, Gregory has shown himself to have expertise in this area
and is very technically capable and great to work with in mm in general, so
am happy to see this :)
