Perhaps then I can see the light, too. With the exception of task coloring, the thread_info is strictly more work and it's possible to do task coloring without thread_info. All performance tests I ran were "about the same" on sparc64, on x86 we really only have one anomaly on one of Linus's SMP x86 machines (fork+exec from lmbench on dual-Athlon) and I'm going to push to investigate that further. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
