rcu head introduce rcu head init on stack
PEM: o Would it be possible to make this bisectable as follows? a. Insert a new patch after current patch 4/6 that defines destroy_rcu_head_on_stack(), init_rcu_head_on_stack(), and init_rcu_head() with their !CONFIG_DEBUG_OBJECTS_RCU_HEAD definitions. This patch performs this transition. Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> CC: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> CC: David S.
