    Subject[PATCH AUTOSEL 4.19 214/219] RDMA/hns: Use GFP_ATOMIC in hns_roce_v2_modify_qp
    Date
    From: YueHaibing <yuehaibing@huawei.com>

    [ Upstream commit 4e69cf1fe2c52d189acdd06c1fd99cc258aba61f ]

    The the below commit, hns_roce_v2_modify_qp is called inside spinlock
    while using GFP_KERNEL. Change it to GFP_ATOMIC.
