    Subject[48/93] netfilter: nf_conntrack: restrict runtime expect hashsize modifications
    2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

    From: Alexey Dobriyan <adobriyan@gmail.com>

    commit 13ccdfc2af03e09e60791f7d4bc4ccf53398af7c upstream.

    Expectation hashtable size was simply glued to a variable with no code
    to rehash expectations, so it was a bug to allow writing to it.
    Make "expect_hashsize" readonly.
