函数名称:kobject_uevent_env - send an uevent with environmental data*@kobj: struct kobject that the action is happening to*@action: action that is happening*@envp_ext: pointer to environmental data* Returns 0 if kobject_uevent_env() is completed with success or the
函数原型:int kobject_uevent_env(struct kobject *kobj, enum kobject_action action, char *envp_ext[])
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct kobject * | kobj | |
enum kobject_action | action | |
char * | envp_ext |
461 | const char * devpath = NULL |
466 | i等于0 |
467 | retval等于0 |
473 | 如果action恒等于重置设备则state_remove_uevent_sent等于1 |
476 | pr_debug("kobject: '%s' (%p): %s\n", kobject_name(kobj), kobj, __func__) |
484 | 如果非设备组指针则 |
485 | pr_debug("kobject: '%s' (%p): %s: attempted to send uevent without kset!\n", kobject_name(kobj), kobj, __func__) |
488 | 返回:负EINVAL |
492 | uevent_ops等于uevent_ops |
495 | 如果uevent_suppress则 |
496 | pr_debug("kobject: '%s' (%p): %s: uevent_suppress caused the event to drop!\n", kobject_name(kobj), kobj, __func__) |
499 | 返回:0 |
502 | 如果uevent_ops且filter则如果非filter(kset, kobj)则 |
504 | pr_debug("kobject: '%s' (%p): %s: filter function caused the event to drop!\n", kobject_name(kobj), kobj, __func__) |
507 | 返回:0 |
513 | 否则subsystem等于kobject_name( & 设备对象) |
515 | 如果非subsystem则 |
516 | pr_debug("kobject: '%s' (%p): %s: unset subsystem caused the event to drop!\n", kobject_name(kobj), kobj, __func__) |
519 | 返回:0 |
529 | 如果非devpath则 |
535 | retval等于 向环境缓冲区添加键值字符串 |
538 | retval等于 向环境缓冲区添加键值字符串 |
541 | retval等于 向环境缓冲区添加键值字符串 |
546 | 如果envp_ext则 |
555 | 如果uevent_ops且uevent则 |
557 | 如果retval则 |
558 | pr_debug("kobject: '%s' (%p): %s: uevent() returned %d\n", kobject_name(kobj), kobj, __func__, retval) |
561 | 转到:exit |
574 | state_add_uevent_sent等于1 |
575 | 退出 |
577 | 当:action恒等于KOBJ_UNBIND |
578 | zap_modalias_env(env) |
579 | 退出 |
581 | 默认 |
582 | 退出 |
587 | retval等于 向环境缓冲区添加键值字符串 |
588 | 如果retval则 |
590 | 转到:exit |
623 | exit : |
624 | 释放内存 |
625 | 释放内存 |
626 | 返回:retval |
