[PATCH v3 0/2] sched: Add cond_resched_rcu_lock() helper

[Simon Horman <horms@verge.net.au>]

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 the two ip_vs functions mentioned above
to use the helper.

Changes since v1 and v2 noted in the changelog of each patch.

  sched: Add cond_resched_rcu_lock() helper
  ipvs: Use cond_resched_rcu_lock() helper when dumping connections
