Hmmm... how so? The only reason for changing the position is because
there's this specific breakage. The goal should be working around
that specific case while keeping the impact minimum on everyone else.
It doesn't matter whether the initial change was good or bad, the
kernel w/ the new layout is already out in the wild and it has been
out there for a while. How is risking changing offsets on most of the
fields on those kernels a good idea? Mimize the changes to work
around the specific case.

Huh? Code which hardcodes layout since 1.5 years ago will definitely
notice.
