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
