函数名称：This function returns an error if it detects any unreliable features of the* stack. Otherwise it guarantees that the stack trace is reliable.* If the task is not 'current', the caller *must* ensure the task is inactive.

函数原型：int arch_stack_walk_reliable(stack_trace_consume_fn consume_entry, void *cookie, struct task_struct *task)

返回类型：int

参数：

50  如果regs则
52  如果ser_mode(regs) determines whether a register set came from user* mode则返回:0
62  如果IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_FRAME_POINTER)则返回:负EINVAL
66  addr等于unwind_get_return_address( & state)
73  如果非addr则返回:负EINVAL
76  如果非consume_entry(cookie, addr, false)则返回:负EINVAL
81  如果unwind_error( & state)则返回:负EINVAL
85  如果非任务标志按位与I am a kernel thread 按位或I am an IDLE thread 的值的值则返回:负EINVAL
