(gdb) list *__cache_free+0x86
0xb1068e39 is in __cache_free (slab.c:3152).
3147                            shared_array->avail += batchcount;
3148                            goto free_done;
3149                    }
3150            }
3151
3152            free_block(cachep, ac->entry, batchcount, node);
3153    free_done:
3154    #if STATS
3155            {
3156                    int i = 0;
(gdb)
