"Information records are supplemental pieces of information that may be "
"provided alongside the generic I<fanotify_event_metadata> structure.  The "
"I<flags> passed to B<fanotify_init>(2)  have influence over the type of "
"information records that may be returned for an event.  For example, if a "
"notification group is initialized with B<FAN_REPORT_FID> or "
"B<FAN_REPORT_DIR_FID>, then event listeners should also expect to receive a "
"I<fanotify_event_info_fid> structure alongside the "
"I<fanotify_event_metadata> structure, whereby file handles are used to "
"identify filesystem objects rather than file descriptors.  Information "
"records may also be stacked, meaning that using the various B<FAN_REPORT_*> "
"flags in conjunction with one another is supported.  In such cases, multiple "
"information records can be returned for an event alongside the generic "
"I<fanotify_event_metadata> structure.  For example, if a notification group "
"is initialized with B<FAN_REPORT_TARGET_FID> and B<FAN_REPORT_PIDFD>, then "
"an event listener should expect to receive up to two "
"I<fanotify_event_info_fid> information records and one "
"I<fanotify_event_info_pidfd> information record alongside the generic "
"I<fanotify_event_metadata> structure.  Importantly, fanotify provides no "
"guarantee around the ordering of information records when a notification "
"group is initialized with a stacked based configuration.  Each information "
"record has a nested structure of type I<fanotify_event_info_header>.  It is "
"imperative for event listeners to inspect the I<info_type> field of this "
