SubjectUmount & quotas
  Hello.

After rewrite on umount code automagical turning of
quotas off stopped working - filesystem was considered
busy.
I would restore the behaviour in 2.4 and probably
in 2.5 move this to userland together with other quota
changes...
Following patch (written by Al Viro) should restore
the behaviour.
