Hi Christoph,
Can you answer some questions about exportfs please?
(1) In linux/exportfs.h, the description of the encode_fh() op says that
"encode_fh() should return the number of bytes stored or a negative error
code such as %-ENOSPC".
This, however, contradicts export_encode_fh(), which returns a member of
enum fid_type instead. I presume the docs are wrong, or at least,
unclear.
(2) Why does exportfs_encode_fh() return the type of the FID? Why not embed
it in the fid struct? It seems that the value has to be handed back to
the decode routine.
(3) Is fat_encode_fh() allowed to return a value not in the fid_type enum?
David
