[RFC PATCH] MAINTAINERS: add kernel/fork.c to relevant sections

[RFC PATCH] MAINTAINERS: add kernel/fork.c to relevant sections

[Lorenzo Stoakes]

Currently kernel/fork.c both contains absolutely key logic relating to a
number of kernel subsystems and also has absolutely no assignment in
MAINTAINERS.

Correct this by placing this file in relevant sections - mm core, exec,
scheduler and pidfd so people know who to contact when making changes here.

scripts/get_maintainers.pl can perfectly well handle a file being in
multiple sections, so this functions correctly.

Intent is that we keep putting changes to kernel/fork.c through Andrew's
tree.

+cc Christian

And Murphy's law dictates that I forget to add the pidfd bit. Fix-patch
included...

Adding pidfd as there's a fair chunk of pidfd code that lives in
kernel/fork.c. Obviously let me know Christian if you feel this makes
sense.

Thanks! And apologies for noise...
