I don't understand what CIFS is doing, and I don't really care. This is the sort of operation where adding a couple of network roundtrips so that the client can obtain the credentials required to perform the operation doesn't really matter. We won't have thousands of chattr(1) calls per second. So I think the principle is more important than the details of the current implementation. And I'm saying that knowing that fixing up FUSE will be my responsibility and it won't be trivial either. Thanks, Miklos
