[PATCH v3 00/10] Make nfsd stats visible in network ns

[Josef Bacik <josef@toxicpanda.com>]

v1: https://lore.kernel.org/linux-nfs/cover.1706124811.git.josef@toxicpanda.com/
v2: https://lore.kernel.org/linux-nfs/cover.1706212207.git.josef@toxicpanda.com/

NOTE: there's still one nfs change in here and it's where I dropped pg_stats, I
assume that's ok for this series, but I can break it out and then follow up with
a removal later if necessary.

v2->v3:
- Split out the nfs and nfsd related changes into their own patches.
- Dropped the change adding sv_stats throuch svc_create()
- Changed the th_cnt to be global, re-arranged it's location.

v1->v2:
- rework the sunprc service creation to take a pointer to the sv_stats.
- dropped ->pg_stats from the svc_program.
- converted all of the nfsd global stats to per-network namespace.
- added the ability to point at a specific rpc_stat for rpc program creation.
- converted the rpc stats for nfs to per-network namespace.

Josef Bacik (10):
  sunrpc: don't change ->sv_stats if it doesn't exist
  nfs: stop setting ->pg_stats for unused stats
  sunrpc: pass in the sv_stats struct through svc_create_pooled
  sunrpc: remove ->pg_stats from svc_program
  sunrpc: use the struct net as the svc proc private
  nfsd: rename NFSD_NET_* to NFSD_STATS_*
  nfsd: expose /proc/net/sunrpc/nfsd in net namespaces
  nfsd: make all of the nfsd stats per-network namespace
  nfsd: remove nfsd_stats, make th_cnt a global counter
  nfsd: make svc_stat per-network namespace instead of global
