I'm just summarizing the comment that goes with the definition of the
time_after etc functions:
include/linux/jiffies.h:88
/*
* These inlines deal with timer wrapping correctly. You are
* strongly encouraged to use them
* 1. Because people otherwise forget
* 2. Because if the timer wrap changes in future you won't have to
* alter your driver code.
