  Well, the message suggests that you edited actual block usage of user and
not his limit. That's why edquota complained and didn't change anything...
So it's nothing related to kernel nor a bug ;).

  As a side note, I always found edquota(8) error prone and I think
setquota(8) is a better tool to do what I need. But I guess it depends on
one's taste.
