Well, having GFP parameters is not a strict kernel convention. There are
places doing it differently and have sleeping and atomic variants of
APIs. I have to say I like the latter more. But given that this leads to
an invasion of API functions here which all do the same under the hood, I
agree it is better to go with a GFP parameter here.
