While I'm a fan of the (c) form myself, I became used to not using it for
kernel code. Except for internal comments that are not intended to be sent
out. This works fine, as checkpatch will complain if I ever forget to remove
them while preparing patches.

The alternative would be to teach checkpatch to complain about FIXME, TODO,
and XXX in comments...

Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.
