Hi Michael,

Do you think it's appropriate to push the first two patches of this patch set to
linux 6.6?

Thanks.
I generally treat patchsets as a whole unless someone asks me to do
otherwise. Why do you want this?
As we discussed, the patch set supporting AF_XDP will be push to net-next.
But the two patchs belong to the vhost.

So, if you think that is appropriate, I will post a new patchset(include the two
patchs without virtio-net + AF_XDP) to vhost. I wish that can be merged to 6.6.
Oh wait 6.6? Too late really, merge window has been closed for weeks.
I mean as a fix. So I ask you do you think it is appropriate?
Sure if there's a bugfix please post is separately - what issues do
these two patches fix? this is the part I'm missing. Especially patch 2
which just adds a new API.

No bugfix. That is the requirement of the supporting AF_XDP.

So please ignore my question. Sorry ^_^.

Thanks.

Then when the 6.7 net-next merge window is open, I can push this patch set to 6.7.
The v1 version use the virtqueue_dma_map_single_attrs to replace
virtqueue_dma_map_page_attrs. But I think we should use virtqueue_dma_map_page_attrs.

Thanks.
Get a complete working patchset that causes no regressions posted first please
then we will discuss merge strategy.
I would maybe just put everything in one file for now, easier to merge,
refactor later when it's all upstream. But up to you.
OK. I will get a working patchset firstly.

Thanks.
