H A DKconfig.preempt63 preemptible. This allows reaction to interactive events by
96 preemptible priority-inheritance aware variants, enforcing
98 non-preemptible sections. This makes the kernel, except for very
100 level interrupt handling) fully preemptible and brings most
111 the softirq is preemptible. This enforces the same per-CPU BLK
116 this if you suspect an error with preemptible softirq and want test
