From 38b0da7522c086f1dcdeda39a2d1849c6a31f518 Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Mon, 26 Dec 2011 15:38:56 +0300 Subject: [PATCH] SUNRPC: create RPC pipefs superblock per network namespace context 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.
