Hi Felipe,

Looks the following 4 patches should have been marked as stable, sorry
for missing that.

b5b6e8c8d3b4 scsi: virtio_scsi: fix IO hang caused by automatic irq vector affinity
2f31115e940c scsi: core: introduce force_blk_mq
adbe552349f2 scsi: megaraid_sas: fix selection of reply queue
8b834bff1b73 scsi: hpsa: fix selection of reply queue

Usually this backporting is done by our stable guys, so I will CC stable
and leave them handle it, but I am happy to provide any help for
addressing conflicts or sort of thing.


Thanks,
Ming
