I took at look at the code in acpiphp you're talking about, and
I'm not sure why you think the above is "ugly". We're talking
about a runtime vs compile time storage for the name, and doing a
kmalloc/sprintf is a pretty standard idiom.
BTW, I did incorporate both Linas' and Willy's comments, by
changing the kmalloc size to an explicit 32, and using snprintf
instead.
In any case, for your particular comment, I think I'm going to
leave it alone for now, and let Greg weigh in with the final
recommendation.
Thanks for the review.
