    Subject[PATCH 3.13 047/198] SUNRPC: Fix a module reference leak in svc_handle_xprt
    Date
    3.13.11.5 -stable review patch.  If anyone has any objections, please let me know.

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

    From: Trond Myklebust <trond.myklebust@primarydata.com>

    commit c789102c20bbbdda6831a273e046715be9d6af79 upstream.

    If the accept() call fails, we need to put the module reference.
