[PATCH 3/5] xfs: merge xfs_ag.h into xfs_format.h

To: xfs@xxxxxxxxxxx
Subject: [PATCH 3/5] xfs: merge xfs_ag.h into xfs_format.h
From: Christoph Hellwig <hch@xxxxxx>
Date: Wed, 26 Nov 2014 20:14:25 +0100
Delivered-to: xfs@xxxxxxxxxxx
In-reply-to: <1417029267-20149-1-git-send-email-hch@xxxxxx>
References: <1417029267-20149-1-git-send-email-hch@xxxxxx>
More on-disk format consolidation.  A few declarations that weren't on-disk
format related move into better suitable spots.
