This patch introduces users of the round_jiffies() function in the networking
code.
These timers all were of the "about once a second" or "about once every X
seconds" variety and several showed up in the "what wakes the cpu up" profiles
that the tickless patches provide. Some timers are highly dynamic based on
network load; but even on low activity systems they still show up so the
rounding is done only in cases of low activity, allowing higher frequency
timers in the high activity case.
The various hardware watchdogs are an obvious case; they run every 2 seconds
but aren't otherwise specific of exactly when they need to run.

suck that in, thanks.

Arjan, btw:
+ if (dst_gc_timer_expires > 4*HZ)
+ mod_timer(&dst_gc_timer,
+ round_jiffies(jiffies + dst_gc_timer_expires));
+ else
+ mod_timer(&dst_gc_timer, jiffies + dst_gc_timer_expires);
^^^^^^^^^^^^^
That line begins "TAB SPACE TAB", and lo' and behold GIT
catch this when I applied it :-) I fixed it up by hand
and reapplied, so don't worry about this instance.
