Something like this? first_bit = find_next_bit(map, nr_bits, -1); zero_bit = find_next_zero_bit(map, nr_bits, first_bit); if (find_next_bit(map, nr_bits, zero_bit) < nr_bits) return -EINVAL; /* non-contiguous bits */ -- Matt Fleming, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
