That comment was directed at Matt's correct suggestion to use
alloc_cyclic, this same suggestion applies to this conflict as well.

The mechanical change of the args is not so bad for a merge commit.

Not quite, I always re-do and verify all your merge resolutions and
send them to Linus as both a raw diff and as an actual merge commit
for him to reference. This way these things are checked in multiple
ways.

It is difficult to run this flow if we don't have an agreed order of
trees, as producing the resolutions for an unmerged tree is not so
straight forward.
