Hello Sagi,

Sorry but I doubt that that patch makes it "impossible" to move controller
reset flow to the NVMe core. There are already several function pointers in
the nvme_ctrl_ops data structure and there is one such data structure per
transport. Had you already considered to add a function pointer to that
structure?

Bart.
