[Qemu-devel] [PATCH v2] scsi: Improve error messages more |
Date: |
Mon, 28 Apr 2014 13:39:13 +0200 |
Remove the "scsi-block:" prefix for error messages as suggested
by Markus.
Improve the previous patch by making the message the same for both
scsi-block and scsi-generic, including the strerror() output in both
and making an explicit reference to SG_IO. Also s/can not/cannot/.
