resumed.os_sched () performs general task switching (task scheduling when task creation, self-deletion and self-blocking), first to determine the switching conditions, if the ISR is not completed, the scheduler is locked or the current task is the highest priority will not be switched. The OS_TASK_SW () in os_sched () is used to save the context, enabling a real go-to-new task execution.osintexit () is used for task scheduling in clock interrupts, similar to os_sched () to determine the switchi
