Hmm. I could add that with #ifdef ATOMIC64_INIT atomic64 #else atomic_t #endif > But adding arbitary limits like this even temporarily is imho > a bad idea. Hmmm yes this could actually develop to be an issue for us. Columbia has 20 Terabytes of memory (some rumors have it that it get up to 500TB but maybe that was just a journalist). But Columbia has only 1TB per 512 CPU cluster addressable directly. So even the biggest box in existence right now will be fine with V19. But V20 will definitely support atomic64. - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
