This patch adds code to handle SKB_GSO_TCPV6 skbs and construct appropriate extra or prefix segments to pass the large packet to the frontend. New xenstore flags, feature-gso-tcpv6 and feature-gso-tcpv6-prefix, are sampled to determine if the frontend is capable of handling such packets.

http://www.realvnc.com/products/enterprise/4.1/ipv6.html IPv6 support in VNC Server E4.1.7/P4.1.2 VNC Server E4.1.7 & P4.1.2 are fully IPv6-aware, but is shipped with IPv6 support disabled by default, for security reasons. IPv6 can be enabled by setting "InTransports=IPv6,IPv4" (the default being IPv4 only), either on the command-line when starting vncserver under Unix Ok.

Starting with 3.7 rc1, my workstation seems to loose ram. Up until (and including) 3.6, used-(buffers+cached) was roughly the same as sum(rss) (taking shared into account). Now there is an approx 6G gap. When the box first starts, it is clearly less swappy than with <= 3.6; I can''t tell whether that is related. The reduced swappiness persists. It seems to get worse when I update

Hi Guys, My users are reporting some issues with memory on our lustre 1.8.1 clients. It looks like when they submit a single job at a time the run time was about 4.5 minutes. However, when they ran multiple jobs (10 or less) on a client with 192GB of memory on a single node the run time for each job was exceeding 3-4X the run time for the single process. They also noticed that the swap space
