I've seen it written a couple of times in this thread, and in the
wikipedia article, that SOME sw raid configs don't support write
barriers.  This implies that some do.  Which ones do and which ones
don't?  Does anybody have a list of them?

I was mainly wondering if sw RAID0 on top of hw RAID1 would be safe.
