函数名称:lush_workqueue_prep_pwqs - prepare pwqs for workqueue flushing*@wq: workqueue being flushed*@flush_color: new flush color, < 0 for no-op*@work_color: new work color, < 0 for no-op* Prepare pwqs for workqueue flushing
函数原型:static bool flush_workqueue_prep_pwqs(struct workqueue_struct *wq, int flush_color, int work_color)
返回类型:bool
参数:
类型 | 参数 | 名称 |
---|---|---|
struct workqueue_struct * | wq | |
int | flush_color | |
int | work_color |
2719 | bool wait = false |
2722 | 如果flush_color大于等于0则 |
2723 | WARN_ON_ONCE(atomic_read( & lush in progress )) |
2724 | atomic_set( & lush in progress , 1) |
2728 | pool等于I: the associated pool |
2730 | spin_lock_irq( & he pool lock ) |
2732 | 如果flush_color大于等于0则 |
2733 | WARN_ON_ONCE(L: flushing color != - 1) |
2735 | 如果nr_in_flight[flush_color]则 |
2742 | 如果work_color大于等于0则 |
2743 | WARN_ON_ONCE(work_color != work_next_color(L: current color )) |
2744 | L: current color 等于work_color |
2747 | spin_unlock_irq( & he pool lock ) |
2750 | 如果flush_color大于等于0且atomic_dec_and_test( & lush in progress )则complete( & lush completion ) |
2753 | 返回:wait |
