From: Nicholas Bellinger <nab at linux-iscsi.org> As requested by Anthony, here is a patch against target-pending/for-next-merge to expose an ABI version to userspace via a new VHOST_SCSI_GET_ABI_VERSION ioctl operation. As mentioned in the comment, ABI Rev 0 is for pre 2012 out-of-tree code, and ABI Rev 1 (the current rev) is for current WIP v3.6 kernel merge candiate code. I think this is what you had in mind, and hopefully it will make MST happy too. The incremental vhost-scsi patches against...

...ack up to the pre IRQ injection conversion levels. I'm not sure why this ended up making so much of a difference post IRQ injection conversion, but setting virtio-queue affinity is now getting us back to pre IQN injection conversion levels. Changes from v1 -> v2: - Expose ABI version via VHOST_SCSI_GET_ABI_VERSION + use Rev 0 as starting point for v3.6-rc code (Stefan + ALiguori + nab) - Fix upstream qemu conflict in hw/qdev-properties.c - Make GET_ABI_VERSION use int (nab + mst) - Drop unnecessary event-notifier changes (nab) - Fix vhost-scsi case lables in configure (reported by paolo) - Convert qd...

From: Nicholas Bellinger <nab at linux-iscsi.org> Hello Anthony & Co, This is the fourth installment to add host virtualized target support for the mainline tcm_vhost fabric driver using Linux v3.6-rc into QEMU 1.3.0-rc. The series is available directly from the following git branch: git://git.kernel.org/pub/scm/virt/kvm/nab/qemu-kvm.git vhost-scsi-for-1.3 Note the code is cut
