    Subject[ 134/184] udf: avoid info leak on export
    2.6.32-longterm review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Mathias Krause <minipli@googlemail.com>

    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.
