Links or it didn't happen.

HINT: I just (for the the third time on this topic) crawled the following:
http://lists.freebsd.org/pipermail/freebsd-current/2013-October/thread.html

Please help me find what you're talking about.

OK... duly noted. Much thanks for dispelling that myth.

Need I remind you... we don't *list* the disks from camcontrol... we just use 
it as a perfunctory
value-add by stealing disk descriptions from it if/when it is describing a disk.

I would hardly call that phenomenological (rather, more of a multi-pass 
cartesian ontological
approach).

Where? by whom? and when?

We've already established that it wasn't in the mailing lists (or at least not 
in -current as you claim).

A great mentor of mine once said...

"Practice makes Perfect? NO! Unattainable. [pause] Practice makes 
*improvement*."

Perfection versus Improvement.

I would be hard-pressed to accept any argument that a regression has occurred.

Threats won't help your cause. Civility is key.

Didn't touch your disk partitioning code.

I have zero plans to. You can keep it (I'll just replace it in-whole when I 
have something better).

Gleb gave me insta-MFC approval.

What we are doing doesn't need to be done (period).
