Actually, rechecking the bug description, I might have rushed. The bug that I encountered is related to the vunmap() but it is only caused when batching is off, while the bug you reported has batching on.
It seems that your sources support batching but do not include b91f108a3d54 (“VMware balloon: Treat init like reset”), which I think would have solved the problem. I don’t see a mainline kernel that supports batching and does not have this patch, so it would be helpful to see the exact module that you use.
Correct. The hash is d7568c130d0d0ff1fc5b364fc879b91f108a3d54, actually, though. Yes, we miss this commit in our code base, but also we've already provided a test kernel with this commit included to the customer. Unfortunately, we have no answer yet.
At least for one customer I can confirm that the kernel built with both d7568c130 and the proposed patch fixes the issue.
Thanks.
