It's one I regularly see, but had forgotten about in this context.
However; you can also fix things by adding asm volatile ("":::"memory");
in places.
But that's not really the point; I would really rather have a cmdline
knob to fix things. That way we can compile the kernel with and without
and look for differences. -fno-unicorns or something :-)
While I understand some compiler people revel in UB and love to make
unicorns happen, I think in this case the produces result is utterly
insane.
