This is needed because dataplane will run during block migration as well. The block device migration code is quite liberal in taking the iothread mutex. For simplicity, keep it the same way, even though one could actually choose between the BQL (for regular BlockDriverStates) and the AioContext (for dataplane BlockDriverStates). When the block layer is made fully thread safe, aio_context_acquire shall go away altogether. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Michael S.
