      md/raid1: fix bio handling problems in process_checks() · 30bc9b53
      NeilBrown 提交于
      Recent change to use bio_copy_data() in raid1 when repairing
      an array is faulty.
      
      The underlying may have changed the bio in various ways using
      bio_advance and these need to be undone not just for the 'sbio' which
      is being copied to, but also the 'pbio' (primary) which is being
      copied from.
      
      So perform the reset on all bios that were read from and do it early.
      
      This also ensure that the sbio->bi_io_vec[j].bv_len passed to
      memcmp is correct.
      
      This fixes a crash during a 'check' of a RAID1 array.  The crash was
      introduced in 3.10 so this is suitable for 3.10-stable.
