> For receive and writes to a disk, sendfile() is not the answer.
Why not? I see current sendfile implementation can not do it, but what
is wrong with this? I think that we should extent sendfile to do such
things in future... (Is there any problem with it?)
You are right. I meant "now, with the current architecture" it makes
no sense to use sendfile for when the disk file is the destination.
It makes sense when full blown writes directly into the page cache are
supported across the whole kernel (they sort of are right now
minimally for the sake of nfs).
