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.
