Really? Hopefully you have a large enough stack then. There are various users who put char str[NR_CPUS] on the stack and a few other data structures also get incredibly big with NR_CPUS arrays. If it's for sparse cpu ids -- x86 handles those with an translation array. -Andi - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
