Subject: [PATCH v6 8/8] RDMA/rxe: Replace l_sk6 with sk6 in net namespace
Date: Fri, 23 Jun 2023 17:57:49 +0800 [thread overview]

In-Reply-To: <20230623095749.485873-1-yanjun.zhu@intel.com>
From: Zhu Yanjun <yanjun.zhu@linux.dev>
The net namespace variable sk6 can be used. As such, l_sk6 can be
replaced with it.
