There is recurring discussion about making sure that for every interface
that takes a jiffie argument, we have a replacement that takes a proper
unit of time (ktime_t, clock_t, timespec, nanoseconds, microseconds, ...).
In short, we have too many ways to express time, and the jiffies are the
least useful one.
