DENIEL Has reported that watching directories through the new fsnotify API,
might miss some events like deletes and that a directory watch is not recursive, which
means that we need to open two fd(s) for each directory in the cache. (Which halves our
fd cache size).
Again from the top of my head, and I know nothing of this subject.
DENIEL please add any information here, so we can talk about it at LSF.
What I have seen was this:
- if dnotify() is used, it gets every events. If used on a
directory, it will get every creation and deletion. But it is not
recursive, so we need to use dnotify on every inode we manage.
- if fanotify is used, it is recursive and by using it on the root
of a filesystem, then you have events from the whole underlying tree.
The trouble is that deletion seem not to be caught.
I do have tests written in C for that.

Philippe
