Hi Christoph, Jens, and Greg. Would you ack these 2 backports to be applied to v4.4 stable? The backports differ from the upstream applied commits in two aspects: 1) use PCI IDs directly rather than nvme quirk infrastructure (which was introduced later, commit 106198edb7 "nvme: add explicit quirk handling", and depends on many further changes, not required for this purpose). 2) use 'struct nvme_dev->tagset' rather than 'struct nvme_ctrl->tagset' (similarly.) This has been built and tested on top of v4.4.70. Thanks, Mauricio Faria de Oliveira IBM Linux Technology Center Guilherme G.
