Looks relatively sane at first glance; busy this week so haven't looked very hard yet. Two thing though... you're mixing proper C types (uint32_t) and the Linux-specific legacy crap types (__u32). Pick one. I won't recommend _which_ one, because if I do I'll make Andrew unhappy. But pick one; don't use both at the same time. Also read Documentation/volatile-considered-harmful.txt and ponder deeply your use of 'volatile' on certain members of struct pps_s. -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
