Hi James, Martin, Paolo, Ming,

multipathing with linux-next is broken since 20190723 in our CI.
The patches fix a memleak and a severe dh/multipath functional regression.
It would be nice if we could get them to 5.4/scsi-queue and also next.

I would have preferred if such a new feature had used its own
new copy scsi_mq_ops_batching instead of changing the use case and
semantics of the existing scsi_mq_ops, because this would likely
cause less regressions for all the other users not using the new feature.
