Well, xfs_get_extsz_hint also still is useful, and you only move it in
the next patch.

Might be worth alaborating why exactly. When I last looked over it I
couldn't make much sense of it.

Might be worth to "demacrofy" it while you're at it, e.g. rewrite it as:
xfs_daddr_t
xfs_fsb_to_db(struct xfs_inode *ip, xfs_fsblock_t fsb)
{
if (XFS_IS_REALTIME_INODE(ip))
return XFS_FSB_TO_BB(ip->i_mount, fsb);
else
return XFS_FSB_TO_DADDR(ip->i_mount, fsb);
}
