[Qemu-devel] [PATCH 0/3] iothread-related fixes for virtio-scsi |

Hi,
here are three patches with iothread-related fixes for virtio-scsi,
with their test cases.
This series fixes the following bugs:
https://bugzilla.redhat.com/show_bug.cgi?id=1656276
https://bugzilla.redhat.com/show_bug.cgi?id=1662508
I also wanted to do prepare a similar one for virtio-blk but I'm
unsure about how to proceed, because I'm unable to detect during
realize() that the blockdev is using a different iothread. This
crashes QEMU:
{ "execute": "qmp_capabilities" }
{ "execute": "blockdev-add", "arguments": {"driver": "null-co", "node-name":
"hd0", "read-only": true}}
{ "execute": "object-add", "arguments": {"qom-type": "iothread", "id":
"iothread0"}}
{ "execute": "object-add", "arguments": {"qom-type": "iothread", "id":
"iothread1"}}
{ "execute": "device_add", "arguments": {"id": "virtio-blk0", "driver":
"virtio-blk", "iothread": "iothread0", "drive": "hd0"}}
{ "execute": "system_reset"}
(wait for the events)
{ "execute": "device_add", "arguments": {"id": "virtio-blk1", "driver":
"virtio-blk", "iothread": "iothread1", "drive": "hd0"}}
Regards,
Berto
