902636
lo_copy_file_range() passes -errno to fuse_reply_err() and then fuse_reply_err()
902636
changes it to errno again, so that subsequent fuse_send_reply_iov_nofree() catches
902636
the wrong errno.(i.e. reports "fuse: bad error value: ...").
902636
902636
Make fuse_send_reply_iov_nofree() accept the correct -errno by passing errno
902636
directly in lo_copy_file_range().
