A bunch of patches are cleaning this up. Since MST wanted do the vhost.ko split up in 3.11, plus your WIP vringh work, so I wanted the fix for 3.10 as minimum as possible. Other users are using memcpy_fromiovec and friends outside net. It seems a good idea to put it in a util library. e.g. crypto/algif_skcipher.c which also depends on NET for it. > Though I can't see why you thought this was a good idea.
