Subject: [PATCH v2 for-next 3/3] RDMA/hns: Remove unused CMDQ member
Date: Thu, 20 May 2021 11:54:36 +0800 [thread overview]
Message-ID: <1621482876-35780-4-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1621482876-35780-1-git-send-email-liweihang@huawei.com>
From: Lang Cheng <chenglang@huawei.com>
The hcr_mutex was used to serialize mailbox post. Now that mailbox supports
concurrency, this variable is no longer useful.
Fixes: a389d016c030 ("RDMA/hns: Enable all CMDQ context")
