OK, the problem is: fuse doesn't store the number indexing the inodes
in i_ino.  This is not entirely trivial to fix: we either supply the
inode numbers to the encoding function explicitly, or use something
like the get_inode callback in generic_fh_to_dentry/_parent.  At which
point I begin to doubt if it's worth the effort to share this code.
After all the encoding/decoding functions are not complicated at all.
