Li Wang,

This looks like very interesting work.  I'm confused, however, by the need 
for a kernel patch here -- it looks like the changes essentially center on 
allowing kernel modules to register new socket option handlers for 
sockets, and that the socket pointer itself isn't handed into the socket 
option handlers.  I don't have a very complete understanding of the LVS 
kernel code yet, but my impression is that maybe you could simply 
substitute a sysctl for each of the get and set options, and avoid a patch 
entirely?  Or perhaps the goal here is to minimize modifications to the 
userland netfilter admin tool?

Thanks,
