[PATCH] Laptop mode control script support for XFS *_centisecs sysctl values.
From: Bart Samwel <bart@samwel.tk>
XFS now uses
/proc/sys/fs/xfs/xfssyncd_centisecs
/proc/sys/fs/xfs/xfsbufd_centisecs
/proc/sys/fs/xfs/age_buffer_centisecs
Here's a patch to support these values in the laptop mode control script.
