It's because:

$ ./scripts/get_maintainer.pl fs/f2fs/super.c
Jaegeuk Kim <jaegeuk@...nel.org> (maintainer:F2FS FILE SYSTEM)
Chao Yu <chao@...nel.org> (maintainer:F2FS FILE SYSTEM)
Nick Terrell <terrelln@...com> (maintainer:ZSTD)
linux-f2fs-devel@...ts.sourceforge.net (open list:F2FS FILE SYSTEM)
linux-kernel@...r.kernel.org (open list)

Do *not* use content regexes (K: zstd) in MAINTAINERS unless you are absolutely
sure you want to be notified about every file that contains your regex.

If you do want to use a content regex anyway, you might want to look into
changing get_maintainer.pl to make them only apply to patches that contain the
regex, as I think that might be what people are expecting it does.
