[PATCH 0/5] Add pidfd support to the fanotify API

Hey Jan/Amir/Christian,

This is the updated patch series for adding pidfd support to the
fanotify API. It incorporates all the suggestions that had come out of
the initial RFC patch series [0].

The main difference with this patch series is that FAN_REPORT_PIDFD
results in an additional info record object supplied alongside the
generic event metadata object instead of overloading metadata->pid. If
any of the fid flavoured init flags are specified, then the pidfd info
record object will follow any fid info record objects.

    function
