Shaohua Li 41743c1f04 md/raid1: skip data copy for behind io for discard request ... discard request doesn't have data attached, so it's meaningless to allocate memory and copy from original bio for behind IO. And the copy is bogus because bio_copy_data_partial can't handle discard request. We don't support writesame/writezeros request so far.
