    Subject[PATCH 4.14 011/115] tipc: fix a missing rhashtable_walk_exit()
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Cong Wang <xiyou.wangcong@gmail.com>

    [ Upstream commit bd583fe30427500a2d0abe25724025b1cb5e2636 ]

    rhashtable_walk_exit() must be paired with rhashtable_walk_enter().

    Fixes: 40f9f4397060 ("tipc: Fix tipc_sk_reinit race conditions")
