From: Zeng Jingxiang <linuszeng@xxxxxxxxxxx>
The variable damon_lru_sort_initialized is always true, causing the
corresponding conditional expression cannot be executed.
Assigning true to damon_lru_sort_initialized here
544 damon_lru_sort_initialized = true;
The value of damon_lru_sort_initialized is always true.
As a result, the following expression cannot be executed.
463 if (!damon_lru_sort_initialized)
464 return rc;
