[PATCH 1/7] nfsd: use "init_net" for portmapper

From: Stanislav Kinsbursky
Date: Mon Dec 10 2012 - 04:18:27 EST


There could be a situation, when NFSd was started in one network namespace, but
stopped in another one.
This will trigger kernel panic, because RPCBIND client is stored on per-net
NFSd data, and will be NULL on NFSd shutdown.
