From 757856d2b9568a701df9ea6a4be68effbb9d6f44 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Thu, 25 Jun 2015 17:47:45 +0300 Subject: libceph: enable ceph in a non-default network namespace Grab a reference on a network namespace of the 'rbd map' (in case of rbd) or 'mount' (in case of ceph) process and use that to open sockets instead of always using init_net and bailing if network namespace is anything but init_net. Be careful to not share struct ceph_client instances between different namespaces and don't add any code in the !CONFIG_NET_NS case. This is based on a patch from Hong Zhiguo .
