#     kmemleak: Do not corrupt the object_list during clean-up
#     
#     In case of an error (e.g. memory pool too small), kmemleak disables
#     itself and cleans up the already allocated metadata objects. However, if
#     this happens early before the RCU callback mechanism is available,
#     put_object() skips call_rcu() and frees the object directly. This is not
#     safe with the RCU list traversal in __kmemleak_do_cleanup().
#     
#     Change the list traversal in __kmemleak_do_cleanup() to
#     list_for_each_entry_safe() and remove the rcu_read_{lock,unlock} since
#     the kmemleak is already disabled at this point. In addition, avoid an
#     unnecessary metadata object rb-tree look-up since it already has the
#     struct kmemleak_object pointer.
#     
#     Fixes: c5665868183f ("mm: kmemleak: use the memory pool for early allocations")
