xfs: introduce xfs_buf_daddr()
Introduce a helper function xfs_buf_daddr() to extract the disk address of the buffer from the struct xfs_buf. This will replace direct accesses to bp->b_bn and bp->b_maps[0].bm_bn, as well as the XFS_BUF_ADDR() macro. This patch introduces the helper function and replaces all uses of XFS_BUF_ADDR() as this is just a simple sed replacement. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.
