Given that these structure members are removed in Patch 1/9, wouldn't
having these lines remain until this revert patch present compilation
errors when applying the patches in this series individually?

For bisectability would it be better to fix-up Patch 1 to also convert
these two flags to req->needs_extra_trb in one shot? Alternatively you
could sandwich Patch 1 between Patch 8 & 9.

Thanks,
Jack
