Subject: [PATCH v2 for-next 1/9] RDMA/hns: Delete unnecessary variable max_post
Date: Tue, 5 Nov 2019 19:07:54 +0800	[thread overview]
Message-ID: <1572952082-6681-2-git-send-email-liweihang@hisilicon.com> (raw)
In-Reply-To: <1572952082-6681-1-git-send-email-liweihang@hisilicon.com>

From: Yixian Liu <liuyixian@huawei.com>

There is no need to define max_post in hns_roce_wq, as it does
same thing as wqe_cnt.
