Quotas are very important to Samba (and Windows) admins.

See e.g.
http://www.samba.org/samba/docs/man/manpages-3/smbcquotas.1.html

But I would defer to Metze and others on the server side to see
whether XFS or the proposed ext4 quotas match the protocol
requirements which Samba has to support.

Does anyone know whether Samba can handle all of the remote quota
admin operations on Linux/XFS today (and local enforcement)?
