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.
