FYI, we were discussing the fix here:
https://lore.kernel.org/all/20251211175101.GA3405942@google.com/
Sami provided a fix to the thread that you can test. It'd be good to know if it
works for you too. But we still have some questions as we are not familiar with
the sparse code.
Sami, would you mind sending a patch to the sparse list and then we can ask
questions there?
