This leads to a deadlock in the serialization process\nas padata_find_next cannot match padata->seq_nr and pd->processed\nbecause the padata instance with overflowed seq_nr will be selected\nnext.\n\nTo fix this, we use an unsigned integer wrap around to correctly sort\npadata objects in scenarios with integer overflow."
