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

From: Simon Horman
Date: Thu Apr 25 2013 - 21:45:36 EST

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.

As suggested by Eric Dumazet.

Simon Horman (2):
sched: Add cond_resched_rcu_lock() helper
ipvs: Use cond_resched_rcu_lock() helper when dumping connections
