Can you find an actual atomic_read code snippet there that is
broken without the volatile modifier?

A whole bunch of atomic_read uses will be broken without the volatile 
modifier once we start removing barriers that aren't needed if volatile 
behavior is guaranteed.

Could you please cite the file/function names so we can
see whether removing the barrier makes sense?

Thanks,
