Thanks for taking a look.

I'll drop this copy_process() approach for upstream.
 
Is the follow-up fix still being tracked in this thread?

  https://lore.kernel.org/all/20260411163556.8567-1-yangfeng59949@163.com/

If so, I can follow the progress there and help test the fix with the
security_* fmod_ret reproducer once it is available.

Thanks,
Shijia
