Instead of needing to change all of the file systems, would it be possible simply to change the quota layer to call the ns_dquot_* functions? It might make your life simpler, and it would certainly reduce the number of filesystem maintainers that would need to look through and review your changes. You'd just have to work with Jan Kara as the quota system maintainer.
