Remove the "scsi-block:" prefix for error messages as suggested
|
|
|
958e1b |
by Markus.
|
|
|
958e1b |
|
|
|
958e1b |
Improve the previous patch by making the message the same for both
|
|
|
958e1b |
scsi-block and scsi-generic, including the strerror() output in both
|
|
|
958e1b |
and making an explicit reference to SG_IO. Also s/can not/cannot/.
