Not exactly the same
[<c0480d4b>] list_locations+0x257/0x2ad
is the only difference

l *list_locations+0x257
0xc1080d4b is in list_locations (mm/slub.c:3655).
3650                                    l->min_pid);

3653                                    n < PAGE_SIZE - n - 60) {
3654                            n += sprintf(buf + n, " cpus=");
