 be able to swap methods automatically and transparently depending on load
 characteristics, but this should not be necessary if delayed logging works as
 designed.
-
-Roadmap:
-
-2.6.39 Switch default mount option to use delayed logging
-	=> should be roughly 12 months after initial merge
-	=> enough time to shake out remaining problems before next round of
-	   enterprise distro kernel rebases
