函数名称:Helper function for call_rcu() and friends. The cpu argument will* normally be -1, indicating "currently running CPU". It may specify* a CPU only if that CPU is a no-CBs CPU. Currently, only rcu_barrier()* is expected to specify a CPU.
函数原型:static void __call_rcu(struct callback_head *head, rcu_callback_t func, bool lazy)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
struct callback_head * | head | |
rcu_callback_t | func | |
bool | lazy |
2594 | WARN_ON_ONCE((unsignedlong)head & (*的长度 - 1)) |
2605 | 返回 |
2608 | next = NULL |
2609 | local_irq_save(flags) |
2610 | rdp等于this_cpu_ptr( & rcu_data) |
2622 | 如果rcu_nocb_try_bypass(rdp, head, & was_alldone, flags)则返回 |
2625 | rcu_segcblist_enqueue( & Segmented callback list, with , head, lazy) |
2639 | __call_rcu_nocb_wake(rdp, was_alldone, flags) |
2640 | 否则 |
2642 | local_irq_restore(flags) |
