Hi all,

After merging the xfs tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/xfs/libxfs/xfs_bmap.c: In function 'xfs_bmap_del_extent_delay':
fs/xfs/libxfs/xfs_bmap.c:4648:20: warning: unused variable 'ifp' [-Wunused-variable]
  struct xfs_ifork *ifp = XFS_IFORK_PTR(ip, whichfork);
                    ^
fs/xfs/libxfs/xfs_bmap.c: In function 'xfs_bmap_del_extent_cow':
fs/xfs/libxfs/xfs_bmap.c:4776:20: warning: unused variable 'ifp' [-Wunused-variable]
  struct xfs_ifork *ifp = XFS_IFORK_PTR(ip, XFS_COW_FORK);
                    ^
