From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> Hi folks, This series contains patches required to update tcm_vhost <-> virtio-scsi connected hosts <-> guests to run on v3.5-rc2 mainline code. This series is available on top of target-pending/auto-next here: git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git tcm_vhost This includes the necessary vhost changes from Stefan to to get tcm_vhost functioning, along a virtio-scsi LUN scanning change to address a client bug with tcm_vhost I ran into.. Also, tcm_vhost driver has been merged into a single source + header file that is now living under /drivers/vhost/, along with latest tcm_vhost changes from Zhi's tcm_vhost tree. Here are a couple of screenshots of the code in action using raw IBLOCK backends provided by FusionIO ioDrive Duo: http://linux-iscsi.org/images/Virtio-scsi-tcm-vhost-3.5-rc2-3.png http://linux-iscsi.org/images/Virtio-scsi-tcm-vhost-3.5-rc2-4.png So the next steps on my end will be converting tcm_vhost to submit backend I/O from cmwq context, along with fio benchmark numbers between tcm_vhost/virtio-scsi and virtio-scsi-raw using raw IBLOCK iomemory_vsl flash. Please have a look vhost + virtio-scsi folks (mst + paolo CC'ed) and let us know if you have any concerns.
