Hello,

  I am trying to implement dentry_to_fh/fh_to_dentry in my fs. What is
the proper return value in dentry_to_fh? I saw that 'fat' returns 3 and
reiserfs returns 3 or 6 depends on needparent flag. I try to copy the
same concept but it does not work. when I try to cat a file, unknown
error 521 is returned. I checked that 521 is EBADHANDLE. 

Any hints?

TIA.

- Joe
