From 4fb6e8ade2c70ef1a13f358963b3298fd8b72bcc Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 28 Nov 2014 14:25:04 +1100 Subject: [PATCH] xfs: merge xfs_ag.h into xfs_format.h More on-disk format consolidation. A few declarations that weren't on-disk format related move into better suitable spots.
