So the question: do you think we also want PIDFD_SIGNAL_SESSION_GROUP?

Thought about this as well and my feeling is to wait until someone asks
for it. Right now, we have a reason to add PIDFD_SIGNAL_PROCESS_GROUP
because of Andy's use-case. If someone has a use-case for session groups
then yes. Otherwise I'd just not bother?

OK, agreed.

and I forgot to mention, if you want to add PIDFD_SIGNAL_PRGP you can
look at __kill_pgrp_info().

Oleg.
