Should we just make the mount helper use the same variable names as the kernel to avoid confusion? That will be an external change (ie, changing a non-static variable) if anyone linked to the mount helper (doubtful, but possible) and it will break their code. -- Peace and Blessings, -Scott. -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
