Subject: [PATCH] quota-tools: add gfs2 support
Date: Wed, 5 May 2010 00:09:10 +0200	[thread overview]
Message-ID: <20100504220910.GA319@lst.de> (raw)

GFS2 implements the XFS interface for setting and reporting the quota
information, and only allows state changes via remount.

Signed-off-by: Christoph Hellwig <hch@lst.de>
