In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Allows you to utilize OS2/LONG namespace on NetWare servers.
Filenames in this namespace are limited to 255 characters, they are
case insensitive, and case in names is preserved. Say Y. You can
disable it at mount time with the -N os2 parameter of ncpmount.
