    Subject[PATCH 5.13 430/800] RDMA/rtrs: Do not reset hb_missed_max after re-connection
    Date
    From: Gioh Kim <gi-oh.kim@cloud.ionos.com>

    [ Upstream commit 64bce1ee978491a779eb31098b21c57d4e431d6a ]

    When re-connecting, it resets hb_missed_max to 0.
    Before the first re-connecting, client will trigger re-connection
    when it gets hb-ack more than 5 times. But after the first
    re-connecting, clients will do re-connection whenever it does
    not get hb-ack because hb_missed_max is 0.

    There is no need to reset hb_missed_max when re-connecting.
    hb_missed_max should be kept until closing the session.

    Fixes: c0894b3ea69d3 ("RDMA/rtrs: core: lib functions shared between client and server modules")
