[PATCH 0/2] Make nfs and nfsd stats visible in network ns

[Josef Bacik <josef@toxicpanda.com>]

Hello,

We're currently deploying NFS internally and have run into some oddities with
our usage of containers.  All of the services that mount and export NFS volumes
run inside of containers, specifically all the namespaces including network
namespaces.  Our monitoring is done on a per-container basis, so we need access
to the nfs and nfsd stats that are under /proc/net/sunrpc.  However these are
only tied to the init_net, which makes them invisible to containers in a
different network namespace.

Fix this so that these files are tied to the network namespace.  This allows us
to avoid the hack of bind mounting the hosts /proc into the container in order
to do proper monitoring.  Thanks,

Josef
