    Subject[PATCH 5.12 465/700] RDMA/hns: Force rewrite inline flag of WQE
    Date
    From: Lang Cheng <chenglang@huawei.com>

    [ Upstream commit e13026578b727becf2614f34a4f35e7f0ed21be1 ]

    When a non-inline WR reuses a WQE that was used for inline last time, the
    remaining inline flag should be cleared.

    Fixes: 62490fd5a865 ("RDMA/hns: Avoid unnecessary memset on WQEs in post_send")
