fsnotify: move events should indicate the event was on a child
inotify: reimplement inotify using fsnotify
fsnotify: handle filesystem unmounts with fsnotify marks
fsnotify: fsnotify marks on inodes pin them in core
fsnotify: allow groups to add private data to events
fsnotify: add correlations between events
fsnotify: include pathnames with entries when possible
fsnotify: generic notification queue and waitq
