Yup, you're right. I guess that explains why the async_io() routine doesn't have the same BUG() calls. All the raid1 calls are to async_io(). I'll put some thought into NOT using the bio_vec array to store the region number. So if the multi-region code works for async_io(), is there any reason we shouldn't just remove the BUG() calls from sync_io(), to keep the interfaces symmetric?
