One question that hasn't been answered AFAIK is how well the current Linux directory change notification API maps to the needs of its principal user (presumably Samba, and kde/gnome file managers), and a loosely related question of how well the change notification API maps to the corresponding network file system protocol operations (TRANSACT_NOTIFY_CHANGE) which is a fairly common operation sent to Samba, and obviously for the cifs/smb2/smb3 case would limit what types of events the client can notify the desktop/file manager about. In particular, the 10 or 15 filter flags, and the (at least) 8 events (add/remove/modify/rename etc.), available in tne network protocol AFAIK have not been matched to see if they match closely to the existing Linux API. -- Thanks, Steve
