Hi all,

here's the first batch of patches for my EH rework.
It modifies the host reset callback for SCSI drivers
such that the final conversion to have 'struct Scsi_host'
as argument becomes possible.

As usual, comments and reviews are welcome.

Hannes Reinecke (24):
  csiostor: use fc_block_rport()
  fc_fcp: use fc_block_rport()
  zfcp: open-code fc_block_scsi_eh() for host reset
  mptfc: simplify mpt_fc_block_error_handler()
  mptfusion: correct definitions for mptscsih_dev_reset()
  mptfc: open-code mptfc_block_error_handler() for bus reset
  qedf: use fc rport as argument for qedf_initiate_tmf()
  bnx2fc: Do not rely on a scsi command for lun or target reset
  ibmvfc: open-code reset loop for target reset
  ibmvfc: use fc_block_rport()
  fnic: use dedicated device reset command
  fnic: use fc_block_rport() correctly
  aic7xxx: make BUILD_SCSIID() a function
  aic79xx: make BUILD_SCSIID() a function
  aic7xxx: do not reference scsi command when resetting device
  aic79xx: do not reference scsi command when resetting device
  snic: reserve tag for TMF
  snic: use dedicated device reset command
  snic: Use scsi_host_busy_iter() to traverse commands
  sym53c8xx_2: split off bus reset from host reset
  ips: Do not try to abort command from host reset
  qla1280: separate out host reset function from qla1280_error_action()
  megaraid: pass in NULL scb for host reset
  mpi3mr: split off bus_reset function from host_reset
