See ufs_quota.c, especially chkdqchg(). It is passed a struct
ucred* parameter, which contains a struct prison* pointer. So I assume
you can make your decision based on that. Of course, the userland
quota management tools and the jail utilities need to be made aware of
the kernel changes.
If it's there, and you can see it, it's real.
If it's not there, and you can see it, it's virtual.
If it's there, and you can't see it, it's transparent.
If it's not there, and you can't see it, you erased it.
