Which is to say, I second your motion to proceed with normal process. As
one would reasonably expect, this driver didn't fall out of the sky
yesterday. It was completed on 15 November 2018 and has been undergoing
multi-party testing since then. I doubt it's bug free (nor was the last
one), but when bugs have turned up in the driver or in iflib at any point
along the way, convergence to root cause and a fix has been same-day, so I
don't think there's anything that walks like an emergency or quacks like an
emergency related to this commit.
