masayuki2009 opened a new pull request #2737:
URL: https://github.com/apache/incubator-nuttx/pull/2737
## Summary
- During reviewing sched_lock() in nxtask_assign_pid(),
I noticed that g_pidhash is not protected by a critical section
- Because g_pidhash is accessed in an interrupt context,
it should be protected by a critical section.
- Actually, nxsched_foreach(), nxsched_get_tcb() and so on
use a critical section.
## Impact
- No impact
## Testing
- Tested with spresense:wifi (non-SMP) and spresense:wifi_smp
