Export receive_fd() so that some modules can use
it to pass file descriptor between processes without
missing any security stuffs.

Which tree is that against?  Because in mainline this won't even build, let
alone work.

Oh, sorry for that. Now I'm based on vhost.git tree. But looks like I
miss Christoph's commit
42eb0d54c08 ("fs: split receive_fd_replace from __receive_fd"). Will
rebase on it in v8.

Thanks,
