DESCRIPTION

16       This function informs debugobjects of a new rcu_head structure that has
17       been allocated as an auto variable on the stack. This function is not
18       required for rcu_head structures that are statically defined or that
19       are dynamically allocated on the heap. This function has no effect for
20       !CONFIG_DEBUG_OBJECTS_RCU_HEAD kernel builds.
