[PATCH] user of the jiffies rounding code: JBD 

This patch introduces a user: of the round_jiffies() function; the "5 second"
ext3/jbd wakeup.

While "every 5 seconds" doesn't sound as a problem, there can be many of these
(and these timers do add up over all the kernel).  The "5 second" wakeup isn't
really timing sensitive; in addition even with rounding it'll still happen
every 5 seconds (with the exception of the very first time, which is likely to
be rounded up to somewhere closer to 6 seconds)
