Hi,
As long as there are locking mechanisms like this:
void
KeAcquireSpinLockAtDpcLevel(kspin_lock *lock)
{
while (atomic_cmpset_acq_int((volatile u_int *)lock, 0, 1) == 0)
/* sit and spin */;
return;
}
inside if_ndis, the whole of NDIS needs to run under one lock. What is the
name of the "NDIS Giant Lock" after that "Giant" is removed from NDIS?
