ROUND_JIFFIES_UP(9)                       Driver Basics                       ROUND_JIFFIES_UP(9)



NAME
       round_jiffies_up - function to round jiffies up to a full second

SYNOPSIS
       unsigned long round_jiffies_up(unsigned long j);

ARGUMENTS
       j
           the time in (absolute) jiffies that should be rounded

DESCRIPTION
       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.
