That's one, yes. But DN_CLOSE has other problems too for the initial scenario --- for example, in NFS (on the server side) there simply isn't any open or close. The client simply stops sending more writes; and a close() doesn't necessarily imply that there is new data (although it would make sense to restrict DN_CLOSE to close of a writable fd, which would _usually_ mean the data had been modified.) --Stephen
