Olga Kornievskaia 0769663b4f NFSv4.1 fix incorrect return value in copy_file_range ... According to the NFSv4.2 spec if the input and output file is the same file, operation should fail with EINVAL. However, linux copy_file_range() system call has no such restrictions. Therefore, in such case let's return EOPNOTSUPP and allow VFS to fallback to doing do_splice_direct(). Also when copy_file_range is called on an NFSv4.0 or 4.1 mount (ie., a server that doesn't support COPY functionality), we also need to return EOPNOTSUPP and fallback to a regular copy. Fixes xfstest generic/075, generic/091, generic/112, generic/263 for all NFSv4.x versions.
