       where errorid is unique to the maintainer and function-name is

       with a simple grep for the short to type string
       maintainer-errorid.  Don't bother with reusing errorids, there are
       lots of numbers out there.
   
       Example: 
       
       reiserfs_panic(
           p_sb, "reiser-29: reiserfs_new_blocknrs: "
           "one of search_start or rn(%d) is equal to MAX_B_NUM,"
