Hi, Been bugging me that I didn't like the v2 of the "improve the usercopy for sendmsg/recvmsg" patch, so I re-did patch 1 here so that I could do a prep patch (patch 2), and finally re-do the usercopy improvement on top of that. Passes my testing, win is actually slightly larger with this change (closer to 10%, so at least it didn't regress. -- Jens Axboe
