Subject: [PATCH v6 07/18] xfs: add fs geometry bit for sparse inode chunks
Date: Mon,  2 Mar 2015 08:27:57 -0500	[thread overview]
Message-ID: <1425302888-4962-8-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1425302888-4962-1-git-send-email-bfoster@redhat.com>

Define an fs geometry bit for sparse inode chunks such that the
characteristic of the fs can be identified by userspace.
