If we can have your "xfs: fall back to native ioctls for unhandled compat
ones" in 5.3, that would be ideal from my side, then I can just drop the
corresponding patch from my series and have the rest merged for 5.4.

The compat_ptr addition is independent of my series, I just added it
because I noticed it was missing, so we can merged that through
the xfs tree along with your other changes, either for 5.3 or 5.4.
