Hi, Jason & Leon
Do you have further suggestion on this patchset.
By the way, eventhough 5 patches from patchset
"[PATCH for-next 0/6] Some bugfixes for hns" has been accepted,
this patchset still depends on recent resent patch
"[PATCH V3 for-next] RDMA/hns: RDMA/hns: Assign rq head pointer when enable rq record db".
Please note this dependency.
Thanks.
