void anchors_init_parents_locked | ( | struct val_anchors * | anchors | ) |
Recalculate parent pointers.
The caller must hold the lock on the anchors structure (say after removing an item from the rbtree). Caller must not hold any locks on trust anchors. After the call is complete the parent pointers are updated and an item just removed is no longer referenced in parent pointers.
anchors,: | the structure to update. |
