[0/4] scsi: remove legacy cmd_list implementation

Message

Hi all,

with the switch to blk-mq we have an efficient way of looking up
outstanding commands via blk_mq_rq_busy_iter().
In this patchset the dpt_i2o and aacraid drivers are switched over
to using that function, and the now obsolete cmd_list implemantation
in the SCSI midlayer is removed.

As usual, comments and reviews are welcome.

Hannes Reinecke (4):
  dpt_i2o: use midlayer tcq implementation
  dpt_i2o: make adpt_i2o_to_scsi() a void function
  aacraid: use blk_mq_rq_busy_iter() for traversing outstanding commands
  scsi: Remove cmd_list functionality
