The latest kernel upstream. Yes, but using mmap, you can map the runtime->status page, and then copy the data through memcpy to overwrite the status->state data, or even more, which is incredible.
Ah, then that's exactly the case my latest patch set covers. Either the first patch or the second patch alone should work. https://lore.kernel.org/r/20220926135558.26580-2-tiwai@suse.de https://lore.kernel.org/r/20220926135558.26580-3-tiwai@suse.de
Could you verify either of them fixes the problem?
thanks,
