[PATCH v2 0/6] vhost-user-blk: Error handling fixes during initialistion |

vhost-user-blk neglects for several properties to check whether the
configured value is even compatible with the backend. This results
sometimes in crashes because of buggy error handling code, and sometimes
in devices that are presented differently to the guest than the backend
would expect and that don't work properly therefore.
This series fixes some of these bugs.
v2:
- Fix error paths in realize() that didn't set errp
- Added vhost_dev_cleanup() back in the error path (more faithful revert
of 77542d43149)
Kevin Wolf (6):
vhost-user-blk: Make sure to set Error on realize failure
vhost-user-blk: Don't reconnect during initialisation
vhost-user-blk: Improve error reporting in realize
vhost-user-blk: Get more feature flags from vhost device
virtio: Fail if iommu_platform is requested, but unsupported
vhost-user-blk: Check that num-queues is supported by backend
