Oh, just to keep anyone interested up to date: It turns out nearly all of the inordinate performance degredation I was seeing in the last set of results which I reported was due to a prefetch weirdness on my ppc64 test system. In particular, the hlist_for_each_entry macro automatically prefetches tmp->next. Since my tests were done with selinux+capability, it was the case that tmp->next was always NULL (which always causes a bad prefetch case on ppc64) and, to boot, never used, since the comparison inside the loop always succeeded and immediately returned the first entry. A new set of results should hopefully be coming next week. -serge - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
