Thanks, Jon.

In general, I like the control and visibility this provides. With this,
I think we're on the verge of warranting a new drivers/nvme/host/sysfs.c
file to keep all the nvme sysfs management in one place.

I don't think anyone is in a rush to see this in the 4.5 merge window,
so I'll load this on a CMB capable machine and provide a more thorough
review in the next week or so.
