If you want to see if a filesystem supports that flag, just use the
/usr/lib/csih/getVolInfo tool:

   $ /usr/lib/csih/getVolInfo .
   Device Type        : 7
   Characteristics    : 20020
   Volume Name        : <root>
   Serial Number      : 2292001085
   Max Filenamelength : 255
   Filesystemname     : <NTFS>
   Flags              : 3e72eff
     FILE_CASE_SENSITIVE_SEARCH        : TRUE

...

     FILE_SUPPORTS_GHOSTING            : FALSE

Is is worth it/possible to extend this getVolInfo to also include the
SSINFO_FLAGS_NO_SEEK_PENALTY flag in the output?-- Regards, Shaddy
