Hi all

I have a question about raid10 resync. The fbio->bi_next isn't null in function
sync_request_write. But the bios' bi_next that read the data from copies is set 
to NULL before sending down to underlying devices in raid10_sync_request. 

I tried to find where links those bios that don't belong to a r10_bio. But I can't
find it. Is it a bug?

Best Regards
Xiao
