From 6b13168b36b6a7f603d962c232f1f2f325705832 Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Mon, 23 Jan 2012 17:26:05 +0000 Subject: NFS: make nfs_client_list per net ns This patch splits global list of NFS clients into per-net-ns array of lists. This looks more strict and clearer. BTW, this patch also makes "/proc/fs/nfsfs/servers" entry content depends on /proc mount owner pid namespace. See below for details. NOTE: few words about how was /proc/fs/nfsfs/ entries content show per network namespace done. This is a little bit tricky and not the best is could be. But it's cheap (proper fix for /proc conteinerization is a hard nut to crack). The idea is simple: take proper network namespace from pid namespace child reaper nsproxy of /proc/ mount creator. This actually means, that if there are 2 containers with different net namespace sharing pid namespace, then read of /proc/fs/nfsfs/ entries will always return content, taken from net namespace of pid namespace creator task (and thus second namespace set wil be unvisible).
