I suppose that would that be an ubuntu-specific patch for apparmor
userspace? I'm assuming the ABI tells userspace which features are
supported, unless this particular feature can be tested for some other
way? Would the patched userspace know not to use these features under
this ABI in a future 4.18+ kernel or a non-Ubuntu pre-4.17 kernel?
I'm just a bit worried about the upgrade path here.
