NAME
       init_rcu_head_on_stack - initialize on-stack rcu_head for debugobjects

SYNOPSIS
       void init_rcu_head_on_stack(struct rcu_head * head);

ARGUMENTS
       head
           pointer to rcu_head structure to be initialized

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