The following patches made over Michael's vhost branch https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git/log/?h=vhost The patches fix issues with vhost-scsi's 256 cmd limit where if the guest sends more than 256 cmds it will get IO errors, or even if exactly 256 are being sent then we can race and get IO errors. The patches also add LUN RESET support so guests that do not support resetting command timers will not get IO errors and offlined devices when the physical device hits temp issues. Jason, you reviewed ever non scsi patch but 2 of them. I was not sure if that was an oversight or you were ok with them. I'm sending this out hoping you were ok with them and forgot to reply (or I guess will be ok with them if you just missed them last time). V4: - really really fix compile errors - dropped threading patches so we can figure that out separately. V3: - fix compile errors - fix possible crash where cmd could be freed while adding it to completion list - fix issue where we added the worker thread to the blk cgroup but the blk IO was submitted by a driver workqueue. V2: - fix use before set cpu var errors - drop vhost_vq_is_setup - include patches to do a worker thread per scsi IO vq
