This addition looks wrong. dev->online_queues is incremented by nvme_init_queue(), but this function only calls that at a point where it is sure to succeed. So why would a failure path need to decrement it?
Thank you very much the catching that. This particular patch is indeed not correct without the following:
161b8be2bd6ab ("nvme-pci: initialize queue memory before interrupts")
Oh, now I see. Do you think that commit is suitable for stable branches?
Ben.
