Subject: scsi-disk: fix cmd.mode field typo
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=c85a7a0057ca454607a40cde991d495e0deec34d;p=qmiga%2Fqemu.git

scsi-disk: fix cmd.mode field typo

The cmd.xfer field is the data length.  The cmd.mode field is the data
transfer direction.

scsi_handle_rw_error() was using the wrong error policy for read
requests.
