ipvs failback patch

[Ranga Nathan <kairanga@xxxxxxx>]

Karl Kopper's Linux Enterprise Cluster talks about the availability of  
a kernel patch to failback from the backup to the master that keeps the 
connections alive.
I could not find it on the linuxvirtualserver.org site. I see the latest 
versions but they are in source format. Somehow I am unable to do rpm 
--rebuild <sourcerpm>
The current version I have is: ipvsadm v1.24 2003/06/07 (compiled with 
getopt_long and IPVS v1.2.0)
Directions appreciated.
