hujun5 3619e61c31 sched: adjust the scheduling strategy ... 1 Only the idle task can have the flag TCB_FLAG_CPU_LOCKED. According to the code logic, btcb cannot be an idle task, so this check can be removed. 2 Optimized the preemption logic check and removed the call to nxsched_add_prioritized. 3 Speed up the scheduling time while avoiding the potential for tasks to be moved multiple times between g_assignedtasks and g_readytorun.
