[PATCH 05/16] xfs: decouple inode and bmap btree header files

To: xfs@xxxxxxxxxxx
Subject: [PATCH 05/16] xfs: decouple inode and bmap btree header files
From: Dave Chinner <david@xxxxxxxxxxxxx>
Date: Mon, 30 Sep 2013 13:07:02 +1000
Delivered-to: xfs@xxxxxxxxxxx
In-reply-to: <1380510433-8353-1-git-send-email-david@xxxxxxxxxxxxx>
References: <1380510433-8353-1-git-send-email-david@xxxxxxxxxxxxx>
From: Dave Chinner <dchinner@xxxxxxxxxx>

Currently the xfs_inode.h header has a dependency on the definition
of the BMAP btree records as the inode fork includes an array of
xfs_bmbt_rec_host_t objects in it's definition.

Move all the btree format definitions from xfs_btree.h,
xfs_bmap_btree.h, xfs_alloc_btree.h and xfs_ialloc_btree.h to
xfs_format.h to continue the process of centralising the on-disk
format definitions. With this done, the xfs inode definitions are no
longer dependent on btree header files.

The enables a massive culling of unnecessary includes, with close to
200 #include directives removed from the XFS kernel code base.
