In linux-6.12.y, commit 5e8438fd7f11 ("scsi: replace blk_mq_pci_map_queues with blk_mq_map_hw_queues") was pulled in as depandency, the fix a9ae6fe1c319 ("blk-mq: create correct map for fallback case") should have just used 1452e9b470c9 ("blk-mq: introduce blk_mq_map_hw_queues") as Fixes, not the other conversion IMO.
What "other conversion"? Sorry, I do not understand, did we take a patch we shouldn't have, or did we miss a patch we should have applied?
If I understand the situation correctly, the problem is that v6.14.25 ships commit 5e8438fd7f11 ("scsi: replace blk_mq_pci_map_queues with blk_mq_map_hw_queues") which introduced a regression for certain virtio configurations. The fixup patch is:
a9ae6fe1c319 ("blk-mq: create correct map for fallback case")
