[PATCH] dosfs: Check error status

[Joel Sherrill]

Assuming this fixes a warning, commit it.

I will review the logs and answer your other question when I get to the workshop this morning. That requires a computer.

I will also revert my change to rfs and start another build sweep so please commit this.
