The kernel support is not in upstream kernel yet.

I hope we will merge this merging patches soon:-)

When is this expected to be merged to mainline?

Comment 3 Mikuláš Patočka 2010-04-28 15:01:18 UTC

Mergeable snapshots is in upstream now. It will be supported by distributions when the pick new kernel and lvm2 packages.
