This shouldn't be a problem because in theory, we will no longer have

If we do, it means there was either a hard failure, or SM was killed.
Either way, SM will be restarted and the cache will populate its meta
fresh then.

will fall back to the previous IO op heavy but mem friendly version.
This also includes a compiler warning fix for smls & smput.
