добавить, удалить или изменить отметку fanotify на объекте файловой системы (add, remove, or modify an fanotify mark on a filesystem object)
Ошибки (баги) (Bugs)
The following bugs were present in Linux kernels before version
3.16:
* If flags contains FAN_MARK_FLUSH, dirfd, and pathname must
specify a valid filesystem object, even though this object is
not used.
* readdir(2) does not generate a FAN_ACCESS event.
* If fanotify_mark() is called with FAN_MARK_FLUSH, flags is not
checked for invalid values.
