函数名称:The CPU has been completely removed, and some other CPU is reporting* this fact from process context. Do the remainder of the cleanup.* There can only be one CPU hotplug operation at a time, so no need for* explicit locking.

函数原型:int rcutree_dead_cpu(unsigned int cpu)

返回类型:int

参数:

类型参数名称
unsigned intcpu
2117  rdp等于per_cpu_ptr( & rcu_data, cpu)
2118  rnp等于This CPU's leaf of hierarchy
2120  如果非IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_HOTPLUG_CPU)则返回:0
2124  rcu_boost_kthread_setaffinity(rnp, - 1)
2126  do_nocb_deferred_wakeup(per_cpu_ptr( & rcu_data, cpu))
2129  tick_dep_clear(TICK_DEP_BIT_RCU)
2130  返回:0
