Subject: [PATCH ipvs-next v3 0/2] sched: Add cond_resched_rcu_lock() helper

Add a helper that for use in loops which read data protected by RCU and
may have a large number of iterations.  Such an example is dumping the list
of connections known to IPVS: ip_vs_conn_array() and ip_vs_conn_seq_next().

This series also updates IPVS to use the helper.

Simon Horman (2):
  sched: add cond_resched_rcu() helper
  ipvs: use cond_resched_rcu() helper when walking connections
