Maybe, maybe not.
The list of MAINTAINERS names returned by get_maintainer.pl is:

Andrew Morton <akpm@...ux-foundation.org> (commit_signer:39/504=8%)
"David S. Miller" <davem@...emloft.net> (commit_signer:38/504=8%)
Greg Kroah-Hartman <gregkh@...uxfoundation.org> (commit_signer:36/504=7%)
Kalle Valo <kvalo@...eaurora.org> (commit_signer:28/504=6%)
Mauro Carvalho Chehab <mchehab@....samsung.com> (added_lines:109/2073=5%,removed_lines:108/779=14%)
Guenter Roeck <linux@...ck-us.net> (removed_lines:48/779=6%)

Doubtful but possible.
I have no idea how many files were modified by whatever
patch was checked, but more files, more maintainers.

Unmaintained files have even more "not quite maintainers",
but get_maintainer.pl lists the names of people that recently
modified those specific files.

I'm not touching stuff right now.  Maybe next month.
