We promised to do this for 2.6.37, and the code looks stable enough to
keep that promise.

 Roadmap:
 
-2.6.37 Remove experimental tag from mount option
-       => should be roughly 6 months after initial merge
-       => enough time to:
-               => gain confidence and fix problems reported by early
-                  adopters (a.k.a. guinea pigs)
-               => address worst performance regressions and undesired
-                  behaviours
-               => start tuning/optimising code for parallelism
-               => start tuning/optimising algorithms consuming
-                  excessive CPU time
-
 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
