      tcm_vhost: Initial merge for vhost level target fabric driver · 057cbf49
      Nicholas Bellinger 提交于
      This patch adds the initial code for tcm_vhost, a Vhost level TCM
      fabric driver for virtio SCSI initiators into KVM guest.
      
      This code is currently up and running on v3.5-rc2 host+guest
      from target-pending/for-next-merge.
      
      Using tcm_vhost requires Zhi's -> Stefan -> nab's qemu vhost-scsi tree here:
