It is well tested - it's been in the bcachefs tree for ages with zero
issues. I'm pulling it out of the bcachefs-prerequisites series though
since Dave's still got it in his tree, he's got a newer version with
better commit messages.

It's a significant performance boost on metadata heavy workloads for any
non-XFS filesystem, we should definitely get it in.
