From e9e5eee8733739f13a204132b502494b3f494f3b Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Mon, 8 Nov 2010 20:05:57 +0900 Subject: IPVS: Add persistence engine to connection entry The dest of a connection may not exist if it has been created as the result of connection synchronisation. But in order for connection entries for templates with persistence engine data created through connection synchronisation to be valid access to the persistence engine pointer is required. So add the persistence engine to the connection itself.
