Subject: [PATCH v2 for-next 1/5] RDMA/hns: Rename wqe buffer related functions
Date: Fri, 6 Mar 2020 10:44:50 +0800 [thread overview]
Message-ID: <1583462694-43908-2-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1583462694-43908-1-git-send-email-liweihang@huawei.com>
From: Xi Wang <wangxi11@huawei.com>
There are serval global functions related to wqe buffer in the hns driver
and are called in different files. These symbols cannot directly represent
the namespace they belong to. So add prefix 'hns_roce_' to 3 wqe buffer
related global functions: get_recv_wqe(), get_send_wqe(), and
get_send_extend_sge().
