Playing around with inotify I have some problems
to generate/receive IN_UNMOUNT-events (using
a self written application and inotify_utils-0.25;
kernel 2.6.13).

Doing:
- mount /dev/hda1 /mnt
- add a watch to the path /mnt/ ("./inotify_test /mnt")
- umount /mnt

results in two events:
1. IN_DELETE_SELF (mask=0x0400)
2. IN_IGNORED (mask=0x8000)

Any ideas?

"/mnt" is not unmounted, stuff inside of it is.

Watch, say, "/mnt/foo/bar" and when /dev/hda1 is unmounted, you will get
an IN_UNMOUNT on the watch.

I think this might work as well:
# mount /dev/hda1 /mnt
# ./inotify_test /mnt/. &
# umount /mnt

That should get the effect you are looking for
