Message-Id: <20190319153921.26780-2-jeremy@azazel.net> Date: Tue, 19 Mar 2019 15:39:20 +0000 From: Jeremy Sowden <jeremy@...zel.net> To: netdev@...r.kernel.org Cc: Steffen Klassert <steffen.klassert@...unet.com>, Herbert Xu <herbert@...dor.apana.org.au>, "David S. Miller" <davem@...emloft.net>, Su Yanjun <suyj.fnst@...fujitsu.com> Subject: [PATCH net v3 1/2] vti4: ipip tunnel deregistration fixes. If tunnel registration failed during module initialization, the module would fail to deregister the IPPROTO_COMP protocol and would attempt to deregister the tunnel. The tunnel was not deregistered during module-exit.
