yup. > Why not use something like do_gettimeofday? (or I'm sure one > of our time keepers can suggest the right thing to use). do_gettimeofday() takes locks, so a) we can't do printk from inside it and b) if you do a printk-from-interupt and the interrupted code was running do_gettimeofday(), deadlock. - 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/
