Name: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.
Proto:int rcutree_dead_cpu(unsigned int cpu)
Type:int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| unsigned int | cpu |
| 2117 | rdp = per_cpu_ptr( & rcu_data, cpu) |
| 2118 | rnp = This CPU's leaf of hierarchy |
| 2120 | If Not IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_HOTPLUG_CPU) Then Return 0 |
| 2124 | rcu_boost_kthread_setaffinity(rnp, - 1) |
| 2126 | do_nocb_deferred_wakeup(per_cpu_ptr( & rcu_data, cpu)) |
