Subject: [PATCH 1/7] nfsd: use "init_net" for portmapper
Date: Mon, 10 Dec 2012 12:19:04 +0300	[thread overview]
Message-ID: <20121210091904.8855.89077.stgit@localhost.localdomain> (raw)
In-Reply-To: <20121210091832.8855.26672.stgit@localhost.localdomain>

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.
