Subject: [PATCH 8/9] xfs: add fsgeom flag for v5 superblock support.
Date: Mon, 27 May 2013 16:38:26 +1000	[thread overview]
Message-ID: <1369636707-15150-9-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1369636707-15150-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

Currently userspace has no way of determining that a filesystem is
CRC enabled. Add a flag to the XFS_IOC_FSGEOMETRY ioctl output to
indicate that the filesystem has v5 superblock support enabled.
This will allow xfs_info to correctly report the state of the
filesystem.
