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") #
