It's possible to create the object in function fetch_valid_cache in line 100.
```lua
local function fetch_valid_cache(lru_obj, invalid_stale, item_ttl,
item_release, key, version)
local obj, stale_obj = lru_obj:get(key)
if obj and obj.ver == version then
return obj
end
if not invalid_stale and stale_obj and stale_obj.ver == version then
lru_obj:set(key, stale_obj, item_ttl)
return stale_obj
end
if item_release and obj then
item_release(obj.val)
end
return nil
end
```
