Subject: [Ocfs2-devel] [PATCH 23/33] ipv4: add ip_sock_set_mtu_discover
Date: Wed, 20 May 2020 21:54:59 +0200	[thread overview]
Message-ID: <20200520195509.2215098-24-hch@lst.de> (raw)
In-Reply-To: <20200520195509.2215098-1-hch@lst.de>

Add a helper to directly set the IP_MTU_DISCOVER sockopt from kernel
space without going through a fake uaccess.
