Currently monotonic_clock()is only used by the hangcheck-timer, and is not used by gettimeofday/clock_gettime (even w/ CLOCK_MONOTONIC). So there may still be an issue there w/ the hangcheck-timer(for x86-64, on i386 the acpi pm timer can be used for monotonic_clock), but its doesn't affect the time related userland interfaces. thanks -john - 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/
