    Subject[patch 34/76] file capabilities: simplify signal check
    -stable review patch.  If anyone has any objections, please let us know.
    ---------------------

    From: Serge E. Hallyn <serue@us.ibm.com>

    Simplify the uid equivalence check in cap_task_kill(). Anyone can kill a
    process owned by the same uid.

    Without this patch wireshark is reported to fail.
