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().
