Which softirq will execute if interrupt is generated on same line: preempted or new softirq?

Question

Following is the sequence of events:

1. interrupt generated at line 1.
2. line 1 disable.
3. ISR executed. Set sofirq bit 1
4. line 1 enable.
5. softirq executes and suddenly interrupts come at line 1.
6. softirq preempted.
7. ISR executed. softirq bit 1 (it was aready 1 as sofirq 1 was not executed completely)
8. line 1 enable.

Now which softirq will execute: preempted one or a new one?

If the preempted one resumes, then it will reset sotirq bit hence new softirq won't execute. Same case if the new softirq executes first.
