Subject: nfsd: use "init_net" for portmapper
X-Git-Tag: v3.8-rc1~20^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f7fb86c6e639360ad9c253cec534819ef928a674;p=profile%2Fivi%2Fkernel-x86-ivi.git

nfsd: use "init_net" for portmapper

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.
