Recognizing SMR HDDs

Now that ken@ has checked in the SMR code I'm wondering how I can see
whether it's having any effect.
I have a 8TB SMR disk in a USB3 enclosure. Does the kernel emit any
sort of trace to indicate that it sees the drive as SMR and takes
that into account?
I have the probe trace enabled in my kernel config, but I don't see
anything special pop out when I turn the drive on.
Does the fact that the drive appears as a /dev/daX play any role?
BTW the disk returns an error when multiple LUNs are probed.
