[PATCH v3 0/2] fanotify: lift pidfd reporting restrictions

[AnonymeMeow]

The pidfd API now supports pidfds for tasks that are not thread group leaders,
but fanotify has not caught up yet. This patch set lifts that restriction and
allows fanotify to report pidfds referring the event-generating thread.

Additionally, this patch set drops the pid_has_task() check before the
pidfd_prepare() call, allowing fanotify to hand out pidfds for reaped tasks,
as suggested by Christian.
