test_bit(GREEN_ETHERNET, &tp->flags));
From local testing, it looks like this test_bit() really confuses the
compiler and forces it to spill much more than it should otherwise need
to.
The good news is that Marco's suggestion of avoiding
instrumened-non-atomic.h (when using plain accesses) sidesteps this, so
I reckon we should go with that.
Should I send that as a fixup, or should I send a new version of the
whole series?
Thanks,
Mark.
