Can you please explain:
- why should we have both acquisition and release semantics for
  __clear_bit(), while none of them is present for __set_bit() ?

- why should we have both acquisition and release semantics for
  __clear_bit() used for purposes other than clear_bit_unlock() ?

Thanks,

Zoltan
