These patches add client and server support for the NFS v4.2 COPY operation, and depend on the new copy_file_range() system call currently scheduled for Linux 4.5. Changes in v2: - Preprocess filehandle op can choose between current_fh and save_fh - NFSD doesnt' need to fsync() after vfs_copy_file_range() call - Mark file as NFS_UNSTABLE in the copy return - The client should send a commit if the file is copied with anything other than NFS_FILE_SYNC - Fix conflicts with CLONE Questions, comments, and other testing ideas would be greatly appreciated!
