Benjamin LaHaise 6cb153cab9 [NET]: use fget_light() in net/socket.c ... Here's an updated copy of the patch to use fget_light in net/socket.c. Rerunning the tests show a drop of ~80Mbit/s on average, which looks bad until you see the drop in cpu usage from ~89% to ~82%. That will get fixed in another patch...
