2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Krause <minipli@xxxxxxxxxxxxxx>
commit 0143fc5e9f6f5aad4764801015bc8d4b4a278200 upstream.
For type 0x51 the udf.parent_partref member in struct fid gets copied
uninitialized to userland. Fix this by initializing it to 0.
