Hi greg k-h,

The git commit id is: bab2f5e8fd5d2f759db26b78d9db57412888f187

But I am bit hesitant if we should revert it because there is a CVE attached
to it: https://ubuntu.com/security/CVE-2024-41024

Not an issue if it is breaking things, let's get it right. We can
trivially reject that CVE if needed.

Also, I am ok with changing userspace if it's necessary. It would be nice if
the authors can clarify the ideal fix here.

No, userspace should not break, that's not ok at all. I'll get someone
to revert this later today, thanks!

Now sent:
https://lore.kernel.org/r/20240815094920.8242-1-griffin@xxxxxxxxx

I'll queue this up later today.

Thanks!
Joel Selvaraj

thanks,
