函数名称:snapshot_open
函数原型:static int snapshot_open(struct inode *inode, struct file *filp)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct inode * | inode | |
struct file * | filp |
47 | nr_calls等于0 |
49 | 如果非hibernation_available()则返回:负EPERM |
52 | lock_system_sleep() |
64 | nonseekable_open(inode, filp) |
65 | data等于snapshot_state |
67 | memset( & handle, 0, sizeof(structsnapshot_handle)) |
70 | swap等于如果swsusp_resume_device则swap_type_of(swsusp_resume_device, 0, NULL)否则负1 |
73 | free_bitmaps = false |
74 | error等于__pm_notifier_call_chain(Going to hibernate , - 1, & nr_calls) |
75 | 如果error则__pm_notifier_call_chain(Hibernation finished , --nr_calls, NULL) |
77 | 否则 |
84 | swap等于负1 |
86 | error等于__pm_notifier_call_chain(Going to restore a saved image , - 1, & nr_calls) |
87 | 如果非error则 |
89 | free_bitmaps等于非error |
90 | 否则nr_calls自减 |
93 | 如果error则__pm_notifier_call_chain(Restore failed , nr_calls, NULL) |
96 | 如果error则atomic_inc( & snapshot_device_available) |
99 | frozen = false |
