All authors have agreed, with the following exceptions:e68d7f6858: wight wasn't asked (I think...), but even if he modified the patch he applied, all code added by it was removed again later.cb7768f9bb: nick could not be reached, but the declarations he added as well as the full timer.c file were deleted again incff81fe498andf800a42e45(did it really take 6 years to remove unused declarations?).ffaf4af230: it looks like this person wasn't contacted, but the code added was removed again inf544bcf105.
