[PATCH 0/2] MAINTAINERS updates for page and slab allocators

[Vlastimil Babka (SUSE)]

Following David's updates [1], perform similar updates for page and slab
allocators to indicate the MM process transition for these
subcomponents. Importantly, add Johannes as a page allocator
co-maintainer.

[PATCH 1/2] MAINTAINERS: add Johannes as the page allocator co-maintainer

[Vlastimil Babka (SUSE)]

Johannes is a long-time expert and reviewer for the page allocator and
has agreed to step up to a co-maintainer role, so do that. Thanks!

Additionally, page allocator is joining the MM transition, following the
MM core updates from David [1].

Patches will be collected in the mm/page_alloc git tree and integrated
via the mm/linux integration tree. To signify the change from Andrew's
mm tree, remove Andrew as M: - get_maintainers will continue CCing him
on most patches via the catch-all MM entry. David prefers not being
added for mail volume reasons.

[PATCH 2/2] MAINTAINERS: move SLAB ALLOCATOR under MEMORY MANAGEMENT

[Vlastimil Babka (SUSE)]

Following David's consolidation of several other MM subcomponents, do
the same for the slab allocator.

Rename the section to MEMORY MANAGEMENT - SLAB ALLOCATOR and move it to
remain in alphabetical order.

Remove Andrew as M: to signify he's not the primary person for picking
patches in this subcomponent. get_maintainers will continue CCing him on
most patches via the catch-all MM entry. David prefers not being added
for mail volume reasons.

Indicate the primary integration branch (slab/for-next) in the T: entry.
It will now be integrrated via the mm/linux integration tree.

Forgot to add:

I couldn't agree more that Johannes Weiner has been making valuable
contributions to the page allocator.

Congratulations and thanks for stepping up as a maintainer, Johannes!

I think you meant the website and this is the mail list, so it stays.
