[$] MAINTAINERS truth and fiction

Since the release of the 5.5 kernel in January 2020, there have been almost87,000 patches from just short of 4,600 developers merged into the mainlinerepository.

Thesemaintainers are documented in a file called, surprisingly, MAINTAINERS.But the MAINTAINERS file, too, must be maintained; how well doesit reflect reality?
