Hi David, The IPVS people needs this patch for net-next to allow to tune the socket buffer for ipvs_sync (the state synchronization that they do from kernel-space). This exports sysctl_wmem_max and sysctl_rmem_max living in net/core/sock.c. So far, they've been using global socket tuning to make them bigger (this avoids overruning the socket under high peak of state-change synchronization). I think this is out of my scope (since it's out of the netfilter tree). Would you acknowledge it, please?
