Hi all,

the fnic driver is walking the list of tags manually, causing frequent
crashes as the block layer doesn't necessarily cleans up requests after
usage.
So switch to scsi_host_busy_iter() to traverse commands avoiding this
problem.

As usual, comments and reviews are welcome.

Hannes Reinecke (3):
  fnic: kill 'exclude_id' argument to fnic_cleanup_io()
  fnic: use scsi_host_busy_iter() to traverse commands
  fnic: check for started requests in fnic_wq_copy_cleanup_handler()
