2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Krause <minipli@xxxxxxxxxxxxxx>
commit fe685aabf7c8c9f138e5ea900954d295bf229175 upstream.
For type 1 the parent_offset member in struct isofs_fid gets copied
uninitialized to userland. Fix this by initializing it to 0.
