When event data type is FSNOTIFY_EVENT_INODE, we don't have a refernece to the mount, so we will not be able to open a file descriptor when user reads the event. However, if the listener has enabled reporting file identifier with the FAN_REPORT_FID init flag, we allow reporting those events and we use an identifier inode to encode fid. The inode to use as identifier when reporting fid depends on the event. For dirent modification events, we report the modified directory inode and we report the "victim" inode otherwise. For example: FS_ATTRIB reports the child inode even if reported on a watched parent. FS_CREATE reports the modified dir inode and not the created inode.
