    Subject[PATCH tip/core/rcu 19/23] rcu head introduce rcu head init on stack
    Date
    From: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>

    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.
