if one of the critical section code (linked list) is under
ISR & another one in kernel thread ? How you will
synchronize for this critical section code ?

Question Posted / nt

Answer Posted / nt

In the kernel thread you need to disable interrupts before
critical section code starts and then enable interrupts
just after critical section ends. In this way u will make
sure that either ISR or kernel thread execute critical
section at a time.
