[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) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
