This is a note to let you know that I've just added the patch titled

KVM: Check the allocation of pv cpu mask

to the 5.8-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...

The filename of the patch is: kvm-check-the-allocation-of-pv-cpu-mask.patch and it can be found in the queue-5.8 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

This patch is not a correct version, so please don’t add this to the stable tree, thanks.

What's wrong with it? That's what landed upstream.

The patch landed upstream is the v1 version. There are some mistakes and shortcomings. The message discussed is

https://lore.kernel.org/kvm/d59f05df-e6d3-3d31-a036-cc25a2b2f33f@gmail.com/

Then, a revert commit was pushed. Here,

https://lore.kernel.org/kvm/CAB5KdObJ4_0oJf+rwGXWNk6MsKm1j0dqrcGQkzQ63ek1LY=...

What is the git commit id of the revert in Linus's tree?

It is not landed Linus'tree yet. Maintainers suggested a revert before 5.9 is released. Message is here:

https://lore.kernel.org/kvm/CAB5KdObJ4_0oJf+rwGXWNk6MsKm1j0dqrcGQkzQ63ek1LY=...

So I think it should not be added to the stable tree now.

Because of some error, I send this mail using my gmail instead of enterprise email. I'm sorry.
