Subject: [PATCHv5 for-rc1 v5 8/8] RDMA/rxe: Replace l_sk6 with sk6 in net namespace
Date: Fri, 28 Apr 2023 17:39:14 +0800	[thread overview]
Message-ID: <20230428093914.2121131-9-yanjun.zhu@intel.com> (raw)
In-Reply-To: <20230428093914.2121131-1-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.
