Function to round jiffies up to a full second
unsigned long __round_jiffies_up(unsigned long j, int cpu);
j
the time in (absolute) jiffies that should be rounded
cpu
the processor number on which the timeout will happen
This is the same as __round_jiffies except that it will never round down. This is useful for timeouts for which the exact time of firing does not matter too much, as long as they don't fire too early.
