The same comments apply for this comment as well.

The config.h should ideally be included in the lapi/quotactl.h instead.

And this is included in the quotactl_var.h so no need to include it here
as well.

The test has .needs_root flag set, so as far as I can tell this will
always return 0, or do I miss something?

Why do we have this here?
