Subject: [PATCH 0/3 net-next] sunvnet: edge-case/race-conditions bug fixes

This patch series contains fixes for race-conditions in sunvnet,
that can encountered when there is a difference in latency between
producer and consumer.

Patch 1 addresses a case when the STOPPED LDC ack from a peer is
processed before vnet_start_xmit can finish updating the dr->prod
state. 

Patch 2 fixes the edge-case when outgoing data and incoming
stopped-ack cross each other in flight. 

Patch 3 adds a missing rcu_read_unlock(), found by code-inspection.

Sowmini Varadhan (3):
  Fix race between vnet_start_xmit() and vnet_ack()
  vnet_ack() should check if !start_cons to send a missed trigger
  Add missing rcu_read_unlock() in vnet_start_xmit
