Subject: [Qemu-devel] [PATCH] iSCSI: Add support for SG_IO to bdrv_ioctl()/iscsi_ioctl()
Date: Tue, 21 Aug 2012 09:59:34 +1000 [thread overview]
Message-ID: <1345507175-7248-1-git-send-email-ronniesahlberg@gmail.com> (raw)
Paolo, List
Please find a patch that adds emulation of SG_IO to the synchronous function
bdrv_ioctl()/iscsi_ioctl().
Previously we have only supported emulation for this ioctl in iSCSI for the
asynchronous function iscsi_aio_ioctl() since that is the only place scsi-generic uses SG_IO.
By adding support for SG_IO to iscsi_ioctl() this makes scsi-block and scsi-disk work too.
Since scsi-block/scsi-disk never worked with iscsi, and only scsi-generic worked, this is not a new regression. So whether this should go in now or wait until post 1.2 is for your disgression.
regards
ronnie sahlberg
