函数名称:Initialize a new grace period. Return false if no grace period required.
函数原型:static bool rcu_gp_init(void)
返回类型:bool
参数:无
1474 | WRITE_ONCE(Time of last GP kthread , jiffies) |
1476 | 如果非READ_ONCE(Commands for GP task. )则 |
1479 | 返回:false |
1481 | WRITE_ONCE(Commands for GP task. , 0) |
1489 | 返回:false |
1507 | raw_spin_lock( & ofl_lock) |
1518 | oldmask等于qsmaskinit |
1522 | 如果非oldmask不等于非qsmaskinit则 |
1523 | 如果非oldmask则 |
1526 | 否则如果rcu_preempt_has_tasks(rnp)则 |
1527 | Necessary to wait for blocked tasks to = true |
1528 | 否则 |
1529 | rcu_cleanup_dead_rnp(rnp) |
1543 | Necessary to wait for blocked tasks to = false |
1544 | 如果非qsmaskinit则rcu_cleanup_dead_rnp(rnp) |
1549 | raw_spin_unlock( & ofl_lock) |
1567 | rcu_gp_slow(gp_init_delay) |
1569 | rdp等于this_cpu_ptr( & rcu_data) |
1582 | 如果mask或Necessary to wait for blocked tasks to 的值且Is this rcu_node a leaf? (rnp)则Similar to rcu_report_qs_rdp(), for which it is a helper function |
1584 | 否则raw_spin_unlock_irq_rcu_node(rnp) |
1587 | WRITE_ONCE(Time of last GP kthread , jiffies) |
1590 | 返回:true |
