    Subject[068/262] kobj_uevent: Ignore if some listeners cannot handle message
    3.0-stable review patch.  If anyone has any objections, please let me know.

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

    From: Milan Broz <mbroz@redhat.com>

    commit ebf4127cd677e9781b450e44dfaaa1cc595efcaa upstream.

    kobject_uevent() uses a multicast socket and should ignore
    if one of listeners cannot handle messages or nobody is
    listening at all.

    Easily reproducible when a process in system is cloned
    with CLONE_NEWNET flag.
