This patchset will list badblocks while we do 'dmsetup status'.

Image that we have mark block 1 and 2 as bad block, run following
command will list all bad blocks:

    $ sudo dmsetup status dust1
    0 33552384 dust 252:17 bypass verbose badblocks list: 1 2

v1->v2:
Realize this logical in dust_status instead dust_message since the
result can return to user directly.


yangerkun (2):
  dm dust: list badblock in dust_status
  dm dust: introduce list badblocks in the rst
