URL: https://github.com/apache/incubator-nuttx/pull/4989#issuecomment-992413920


   This commit is abandoned, I will do a new one soon.
   
   The BUG is as follow:
   
   1. Suppose there are two ready tasks t1 and t2 have the same priority, and t1 is the running.
   2. A new, higher priority task t0 (such as hpwork) is ready, then switch to t0.
   3. After t0 is suspended, then switch to t1 and reset the t1's timeslice.
   4. goto 2
   
   The t2 will have no chance to run.
