Hi Brice,

Does that mean it’s up to users to add such an argument to
‘kernel-arguments’? If so, we should probably document it (though
that’s not a blocker for this series.)

Sounds good.
I haven’t actually tested it but the patch series LGTM! It’s a much
welcome improvement.

Make sure to add this line in the commit log of patch #2.
Thank you!
