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.
