   work_s has 6 int before modification, need 7 int, so each work requre additional 4 bytes. but we can use union like this to achieve the same size as before:
   ```
   work_s
   {
     union
     {
        struct sq_entry_s sq;
        struct wdog_s timer;
     };
     worker_t  worker;
     FAR void *arg;    
   };
   ```
   since sq and timer is never used at the same time.
