Subject: [PATCH v3 17/18] xfs: add fs geometry bit for sparse inode chunks
Date: Fri,  6 Feb 2015 14:53:04 -0500	[thread overview]
Message-ID: <1423252385-3063-18-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1423252385-3063-1-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.
