It would be good to have more M's here in the case Suren is away or
whatever.

I have worked on the mmap locking due to the maple tree addition, and I
have helped with vma locking in some areas.

Lorenzo wrote the locking document, which Suren pointed out last mmap
lock meeting and does make locking changes.

Are there others that could be M here?

Shakeel and/or Jann might be good additions to this list somewhere
(looking at the edits to the file).
