Subject: [PATCH 18/33] ipv4: add ip_sock_set_tos
Date: Wed, 13 May 2020 08:26:33 +0200 [thread overview]
Message-ID: <20200513062649.2100053-19-hch@lst.de> (raw)
In-Reply-To: <20200513062649.2100053-1-hch@lst.de>
Add a helper to directly set the IP_TOS sockopt from kernel space without
going through a fake uaccess.
Signed-off-by: Christoph Hellwig <hch@lst.de>
