Hi Ming (and all), Your series "scsi: virtio_scsi: fix IO hang caused by irq vector automatic affinity" which forces virtio-scsi to use blk-mq fixes an issue introduced by 84676c1f. We noticed that this bug also exists in 4.14.y (as ef86f3a72adb), but your series was not backported to that stable branch. Are there any plans to do that? At least CoreOS is using 4.14 and showing issues on AHV (which provides an mq virtio-scsi controller). Thanks, Felipe
