Could you use something like a bunch of RAM disks on a large memory system to stress test the spin_lock? Esp if you put in some dm-faulty devices on top?
I tried with block ram device directly, though I didn't use dm-faulty devices on top of raid5.
REally load it down with FIO tests, and then turn on a faulty disk to see how it reacts?
Thanks, I will give it a try. Cheers, Guoqing
