The NFSv4.2 COPY interface is a train wreck. At least for Linux I'd expect us to simply ignore it and only implement my new CLONE operation with sane semantics. That is unless someone can show some real life use case for the inter server copy, in which case we'll have to deal with that mess. But getting that one right at the VFS level will be a nightmare anyway. Make this a vote from me to not support partial copies and just return and error in that case. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
