similar to: [PATCH 4/6] virtio: export more headers to userspace

Rusty, is there a reason why we dont export the virtio headers for 9p, balloon, console, pci, and virtio_ring? kvm uses make sync, but I think it is still useful to heave these headers exported as they might be useful for other userspace tools. I dont export virtio.h, because it does not seem to have useful information for userspace and it requires scatterlist.h which is also not exported.

It makes perfect sense: you're overthinking it. It just means that copying the BSD headers outside Linux is encouraged. And it's clearly nonsensical to claim the GPL on kernel headers means that userspace

virtio_balloon.h exports "u16" and "u64" to userspace. Use "__u16" and "__u64" instead. Signed-off-by: Paul Bolle <pebolle at tiscali.nl> --- 0) Tested with a kernel build. 1) Both types are used in this header for quite some time now. So is my patch flawed or doesn't userspace actually use virtio_balloon.h? include/uapi/linux/virtio_balloon.h

Dunno - people like to do that now, it seems. In any case, cleanups and unifications like that would definitely help if we decide to do that because, in this particular example, we have only one

The get_buf() API sets the second arg to the number of bytes *written* by the other side; in this case it should be zero as these are output buffers. lguest gets this right (obviously kvm's console doesn't), resulting in continual buildup of console writes.
