[PATCH] Increase xfsbufd_centisecs when in laptop mode
From: Bart Samwel <bart@samwel.tk>
The attached patch is the outcome of a discussion with Nathan.
When laptop mode is active, there is no need for XFS to wake up xfsbufd (the
daemon that flushes buffers that are too old) too often. The default is once
every second, this patch makes laptop mode do it once every 30 seconds.
