Why can they co-exist now? XFS does not use the VFS quota
code, and you've made no other changes to XFS so I can't see how you
can make that assertion. There's a current patchset under review
that allows XFS to have co-existing group and project quotas - it's
complex, changes the on-disk format and requires userspace tool
support (e.g. mkfs, repair, xfs_db, etc).

So I can't see how this works with XFS at all...

Cheers,

Dave.

Yes, you right, let's just drop that patch at all.
