This confused me at first, because neither function is mentioned in the patch. > As we do not rely on the sortedness while building the > list, we pick the "append and sort at the end" as it > has better worst case execution times. It took me some time to see that you were rejecting the two solutions you listed in the first paragraph, and are instead using a third (that you describe in this paragraph). The code itself looks fine. In the future, I think that it's better if this type of patch went into its own patch set - this seems independent of the concerns of this patch set, so splitting up keeps patch sets small.
