Description

As shown:

#define LFSCK_RBTREE_BITMAP_SIZE        PAGE_CACHE_SIZE
#define LFSCK_RBTREE_BITMAP_WIDTH       (LFSCK_RBTREE_BITMAP_SIZE << 3)
#define LFSCK_RBTREE_BITMAP_MASK        (LFSCK_RBTREE_BITMAP_SIZE - 1)

In fact, the LFSCK_RBTREE_BITMAP_MASK should be "(LFSCK_RBTREE_BITMAP_WIDTH - 1)".
