round_jiffies_up - function to round jiffies up to a full second

unsigned long round_jiffies_up(unsigned long j);
ARGUMENTS¶
j
the time in (absolute) jiffies that should be
rounded

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.
