Date: Tue, 10 Jun 2014 12:44:12 +0200 From: Mateusz Guzik <mguzik@...hat.com> To: Trond Myklebust <trond.myklebust@...marydata.com> Cc: linux-nfs@...r.kernel.org, linux-kernel@...r.kernel.org, stable@...r.kernel.org.#.3.4+ Subject: [PATCH] NFS: populate ->net in mount data when remounting Otherwise the kernel oopses when remounting with IPv6 server because net is dereferenced in dev_get_by_name. Use net ns of current thread so that dev_get_by_name does not operate on foreign ns. Changing the address is prohibited anyway so this should not affect anything.
