Subject: xfsaild causing 30+ wakeups/s on an idle system since 2.6.25-rcX

Hi,

xfsaild is causing many wakeups, a quick investigation shows
xfsaild_push is always
returning 30 msecs timeout value.

This is on an idle system, running only gnome, and gnome-terminal.

I suggest changing the timeout logic in xfsaild to be more power
consumption friendly.

See below my original report to the powerTOP mailing list.

Best regards,
--Edwin
