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
