Comment 7 for bug 723518

Lucid SRU Justification:

The IN_DELETE_SELF mask for inotify_add_watch indicates that an event
should be emitted when the watched path is deleted, however, this does
not happen on an eCryptfs mount.

To reproduce:

mkdir upper lower
sudo mount -t ecryptfs lower upper

and compile and run the following test program in the upper directory:

This test program hangs waiting for the IN_DELETE_SELF event that never
occurs.
