Now that we no longer use odd internal return codes, we can
heave the translation code over the side, and just pass the
error code back up the call chain.

Why are you adding this initializer? It just disables static analysis
warnings about uninitialized variables and it creates a static analysis
warning about unused assignments.

If ffsMapCluster() fails then we return success now. Is that
intentional?

Use -ENOTEMPTY rather than -EEXIST for attempting to remove
a directory that still has files in it.
