+Subject: [PATCH] libhns: Fix the exception branch of wr_start() is not locked

+driver inclusion
+category: feature
+bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/IB66RT
+
+------------------------------------------------------------------
+
+The provider should provide locking to ensure that ibv_wr_start()
+and ibv_wr_complete()/abort() form a per-QP critical section
+where no other threads can enter.
+
+The exception branch of wr_start() is not locked, fix it here.
+Because check_qp_send () does not require lock protection,
+hns_roce_spin_lock () is placed after check_qp_send ().
+
+Fixes: 36446a56eea5 ("libhns: Extended QP supports the new post send mechanism")
