Your patch was actually quite different. It did implement prjquota option
but the option did something else than in my patch... In your patch you
implemented prjquota option to match the behavior of original quota in
normal files. In my patch I've implemented behavior of prjquota option to
behave similarly as in XFS - i.e. enable enforcement of project quotas when
project quota feature is enabled.
