That's why we check pci_dev_is_disconnected() in pci/access.c
But if the DISCONNECTED bit doesn't get set, it makes me wonder how
solid things currently are.
I don't see any problem by setting this bit as long as the link is
down regardless of the drive presence state and clearing it on link
recovery.
Is there a problem with this approach? I'm catching up with this
thread.
pcie_do_fatal_recovery() doesn't query presence as an example.
