I found a small issue on the client with generic/432 when testing a server that supports COPY/CLONE but doesn't have the open file descriptor cache. Our current knfsd server's cache causes the server to not immediately hand out a read delegation after a COPY/COMMIT, CLOSE, OPEN, so I suspect our normal testing didn't catch this issue. The client bug can be exposed by adding 5 second delays after xfs_io commands in generic/432, which gives the server enough time to clean up the cache and give the delegation.
