Following up on:

Here is a backport series targeting origin/linux-6.6.y that closes
the information leak described in the above thread. It passes basic
NFSD regression testing.

Review comments welcome.   

Chuck Lever (2):
  NFSD: Rewrite synopsis of nfsd_percpu_counters_init()
  NFSD: Fix frame size warning in svc_export_parse()

Josef Bacik (10):
  sunrpc: don't change ->sv_stats if it doesn't exist
  nfsd: 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
