It's an RFC, and so i've just done the minimum I need to do to
verify it is working corectly. Indeed, I'm not sure it is all there
yet, as I haven't tested increased inode alignments on older
kernels. So I'm not sure whether it will need a feature bit or
not yet.
The test matrix of having to test everything on v4 and v5 is just
nasty, especially if we are talking about prototyping code. I'd much
prefer to bring things to v5 filesytsems where we have much lower
exposure and risk of corruption problems, and then when we know it's
solid because of the QA we've done on it, then we can expose the
majority of the XFS userbase to it by bringing it back to v4
filesystems.
As i've said before - if someone wants to bring new features to v4
filesystems sooner than I do, then they need to step up and do the
work themselves, because I don't have the time and resources to
fully verify new features on v4 filesystem formats...
Cheers,
Dave.
