[PATCH 1/7] SUNRPC: create RPC pipefs superblock per networknamespace context

From: Stanislav Kinsbursky
Date: Fri Oct 28 2011 - 10:24:33 EST

This is the initial step of RPC pipefs virtualization. It changes nothing to
current pipefs behaviour except that mount of pipefs in other than init_net
network namespace context will provide only root tree. No other dentries will
be visible.
