 * Macros:
 *
 *  cifs_errIsError( E )  - Returns TRUE if E is in the Error catagory.
 *  cifs_errIsWarn( W )   - Returns TRUE if W is in the Warning category.
 *  cifs_errIsInfo( I )   - Returns TRUE if I is in the Information category.
 *  cifs_errClass( E )    - Returns the error class of error code E.
 *  cifs_errCode( E )     - Returns the error number (positive int) of E.
 *
 *  The cifs_errClass() macro allows you to do things like this:
 *
 *    switch( cifs_errClass(err) )
 *      {
 *      case cifs_errERR:  return( "Error: " );
 *      case cifs_errWARN: return( "Warning: " );
 *      case cifs_errINFO: return( "Info: " );
 *      }
 *    return( "Unknown Error Class: " );
