Sure, but I don't think that matters for this case.  While consume is
a problem for the C Standard, the Linux kernel has its own memory
model which makes extensive use of consume.  This works because
there's more control over the systems on which the kernel runs than
there is for C in general: the same is true for us.  Bear in mind that
this bug has been present for years.

The first rule for back-porting is "do no harm."  I can be sure that
this patch does no harm, but I cannot be sure of a more complex back-
port.
