Since Firefly, the MDS rewrites TMAPs to OMAPs whenever a directory is updated, so a pre-firefly filesystem might already be all OMAPs, or might still have some TMAPs -- there's no way to know without scanning the whole system. If you're think you might have used a pre-firefly version to create the filesystem, then run the tool: if there aren't any TMAPs in the system it'll be a no-op.
