Short version: No. For that particular purpose, currently you''d better
stick with wither LVM+ext4 or zfs.
Long version: IIRC Arne Jansen posted patches for subvolume/qgroup
quota support, so it can be used for what you need, up to a certain
degree. It''s not as complete as zfs (which also supports reservation
in addition to quota), and it hasn''t reached upstream kernel yet (at
least it''s not in 3.1-rc9).
