ROUND_JIFFIES_UP_REL(9) Driver Basics ROUND_JIFFIES_UP_REL(9)NAME
round_jiffies_up_relative - function to round jiffies up to a full second
unsigned long round_jiffies_up_relative(unsigned long j);
the time in (relative) jiffies that should be rounded
This is the same as round_jiffies_relative 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.
