@pkarashchenko We ran in to an issue with an older version of the PI code
and I am wondering if it exits in the latest code?
sched_lock() is not respected on a call to sem_post that reprioritizes
Causing code like following to not work
```
sched_lock();
nxsem_post(&dev->d_bfsem); ------------>Swapped out if there is
a higher priority waiter.
ret = nxsem_wait(&dev->d_wrsem);
sched_unlock();
```
Has this been fixed? If so, can you point me to the mitigation?
