I also think that is stupid to change all of the file systems with those

At first I have tried to change the quota layer by adding
ns_dquot_<foo>() to the corresponding dquot_<foo>(), it could works on
ext4, and it should works on other file systems which are tightly bound
to VFS quota IMHO.
However, XFS has its own quota management subsystem, with looser binding
to VFS quota. That's why am trying to export those routines over all
the file systems and CC to the maintainers, sorry for the noise.
No worries about the noise. I was just trying to suggest something
that might be easier for you.
As near as I can tell XFS doesn't use the fs/quota functions at all,
yes? But if you add it into the fs/quota functions, it should get you
integration with ext2, ext3, ext4, jfs, ocfs2, and reiserfs. Yes?
