Two of the most important (at least to my eye) are: http://marc.info/?l=3Dlinux-netdev&m=3D136241595507566&w=3D2 and http://marc.info/?l=3Dlinux-netdev&m=3D136392337900604&w=3D2 Three more caught my eye as I was poking through the commit histories: http://marc.info/?l=3Dlinux-netdev&m=3D136382407631873&w=3D2 http://marc.info/?l=3Dlinux-netdev&m=3D136639199530624&w=3D2 http://marc.info/?l=3Dlinux-netdev&m=3D136580231922814&w=3D2 And that's just the tip of the iceberg! I expect to have to rerun a ton of benchmarks as a result of these changes, and to have to throw out a lot of older data. Please plan on having to do the same after these kernels are released.... --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
