SubjectRe: [PATCH v2 1/5] pidfd: verify task is alive when printing fdinfo

So you decided to add a helper ;) OK, but note that its name is very
confusing and misleading. Even more than pid_alive() we already have.

What does "alive" actually mean? Say, task_alive(pid, PIDTYPE_SID) == F
after fork(). Then it becomes T if this task does setsid().

And why task_ if it accepts pid+pid_type? May be pid_has_task() or
something like this...

OK, since I can't suggest a better name I won't really argue. Feel free
to add my reviewed-by to this series.

Oleg.
