  * The following locks and mutexes are used by kmemleak:
  *
  * - kmemleak_lock (raw_spinlock_t): protects the object_list modifications and
- *   accesses to the object_tree_root. The object_list is the main list
- *   holding the metadata (struct kmemleak_object) for the allocated memory
- *   blocks. The object_tree_root is a red black tree used to look-up
- *   metadata based on a pointer to the corresponding memory block.  The
- *   kmemleak_object structures are added to the object_list and
- *   object_tree_root in the create_object() function called from the
- *   kmemleak_alloc() callback and removed in delete_object() called from the
- *   kmemleak_free() callback
+ *   accesses to the object_tree_root (or object_phys_tree_root). The
+ *   object_list is the main list holding the metadata (struct kmemleak_object)
+ *   for the allocated memory blocks. The object_tree_root and object_phys_tree_root
+ *   are red black trees used to look-up metadata based on a pointer to the
+ *   corresponding memory block. The object_phys_tree_root is for objects
+ *   allocated with physical address. The kmemleak_object structures are
+ *   added to the object_list and object_tree_root (or object_phys_tree_root)
+ *   in the create_object() function called from the kmemleak_alloc() (or

+ *   the kmemleak_free() callback
  * - kmemleak_object.lock (raw_spinlock_t): protects a kmemleak_object.
  *   Accesses to the metadata (e.g. count) are protected by this lock. Note
