Tejun Heo 7175c61cc6 idr: explain WARN_ON_ONCE() on negative IDs out-of-range ID ... Until recently, when an negative ID is specified, idr functions used to ignore the sign bit and proceeded with the operation with the rest of bits, which is bizarre and error-prone. The behavior recently got changed so that negative IDs are treated as invalid but we're triggering WARN_ON_ONCE() on negative IDs just in case somebody was depending on the sign bit being ignored, so that those can be detected and fixed easily. We only need this for a while. Explain why WARN_ON_ONCE()s are there and that they can be removed later.
