Roadmap:



2.6.35 Inclusion in mainline as an experimental mount option

	=> approximately 2-3 months to merge window

	=> needs to be in xfs-dev tree in 4-6 weeks

	=> code is nearing readiness for review



2.6.37 Remove experimental tag from mount option

	=> should be roughly 6 months after initial merge

	=> enough time to:
