Log the ALUA state change unit attention correctly with
the message log and emit an event to allow user-space
tools to react to it.

Would you mind changing this to "Asymmetic access state changed",
since that is the actual text in the T10 spec?

And could you change this to "ASYMMETRIC_ACCESS_STATE_HAS_CHANGED"?

Seems like a good idea.  As I mentioned yesterday, I have a patch set
that rescans the device when the ALUA state transitions to an ACTIVE
state, if the capacity could not be obtained when the device was
previously probed.  This could be made more generalized, too.
But I don't have the HW to test it, and I'm waiting for the vendor
to get back to me.

Looking at this closely, I didn't get the SDEV_UA text
right in my previous review comment, and I think that
additional enum values really ought to be added to the
end, after existing ones, and code that handles them
should follow suit.  So, here's an adjusted patch...
