Hi,

Please consider apply both fix for bio order, it fixes dead lock in
MD/DRBD.

I backported to 4.4, and also tested on 4.4.50.

Both patches apply cleanly on 4.4.59.

NeilBrown (2):
  blk: improve order of bio handling in generic_make_request()
  blk: Ensure users for current->bio_list can see the full list.
