The only reason why I kept this was to avoid duplicating the same comment
in two places. I thought that an inline function would be better than that.

That's already the case. Sorry but I have to ask, do you read my patches
before commenting? I have the feeling that is the second time that you ask
for something that was already done in the patch.

As mentioned I thought about it. But then decided that an inline function would
be better to have the comment just in one place. I don't have a strong opinion
though so I could change if others agree that duplicating the comment is better.
