From: Haoyue Xu <xuhaoyue1@hisilicon.com> mainline inclusion from mainline-v5.15-rc6 commit fd92213e9af3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4QOTS CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?id=571... --------------------------------------------------------------------- We set the init CQ status to ARMED before. As a result, an unexpected CEQE would be reported. Therefore, the init CQ status should be set to no_armed rather than REG_NXT_CEQE.
