Subject: [Ocfs2-devel] [PATCH 26/28] ipv6: add ip6_sock_set_recvpktinfo
Date: Thu, 28 May 2020 07:12:34 +0200 [thread overview]
Message-ID: <20200528051236.620353-27-hch@lst.de> (raw)
In-Reply-To: <20200528051236.620353-1-hch@lst.de>
Add a helper to directly set the IPV6_RECVPKTINFO sockopt from kernel
space without going through a fake uaccess.
Signed-off-by: Christoph Hellwig <hch@lst.de>
