Just convenient to cut a clean kernel and say that if people use
v4.7 or later they don't see the issue. Else you have to tell them to
use one or another stable kernel (which they should, for products etc)
which complicates things.

But you're right, it's no *big* deal in that sense.

Johan does use some alarmin language like destroyed hardware in
the patch description making me feel the issue is urgent though.
Given how long it has been there I don't know if it is really urgent
in practice and not only in theory.

Yours,
