Maybe I am missing something here, but what is the project here?

Is it:

1. To modify the Samba VFS to support change notify if the underlying
file system supports it? In this case, it is my understanding that the
VFS already contains such support.

2. To modify the CIFSFS to pass through change-notify events to
inotify requests that applications might be using?
