Asias He af0d9187f6 tcm_vhost: Use ACCESS_ONCE for vs->vs_tpg[target] access ...

In vhost_scsi_handle_vq:

      tv_tpg = vs->vs_tpg[target];
      if (!tv_tpg) {
              ....
              return
      }

      tv_cmd = vhost_scsi_allocate_cmd(tv_tpg, &v_req,

1) vs->vs_tpg[target] might change after the NULL check and 2) the above
line might access tv_tpg from vs->vs_tpg[target]. To prevent 2), use
ACCESS_ONCE. Thanks mst for catching this up!
