Grumble. By not passing an FSP into READDIR etc we make it harder for OEMs to avoid modifying Samba

There is a way to get there from here :-). It's ugly, but doable.
vfs_readdir() takes an SMB_STRUCT_DIR *, which should have been returned
from vfs_fdopendir(). vfs_fdopendir *does* take a fsp, and so you can
add an associative cache inside opendir that links fsp's to SMB_STRUCT_DIR *
pointers. The inside vfs_readdir() do the fsp lookup.
Of course I'm happy to review any changes to the VFS for 4.2.x (going
into master now !).
