[PATCH 00/18] Unify and simplify SCSI request initialization

[Bart Van Assche <bart.vanassche@sandisk.com>]

Hello Martin and James,

The patches in this series unify scsi-mq and scsi-sq request initialization,
significantly simplify request initialization and fix a recently introduced
bug in the request initialization code. Please consider these patches for
kernel v4.13.

Thanks,

Bart.

Bart Van Assche (18):
  block: Introduce blk_queue_cmd_size()
  bsg: Check private request size before attaching to a queue
  pktcdvd: Check private request size before attaching to a queue
  cdrom: Check private request size before attaching to a queue
  nfsd: Check private request size before submitting a SCSI request
  scsi: Make scsi_ioctl_reset() pass the request queue pointer to
    blk_rq_init()
  block: Introduce request_queue.initialize_rq_fn()
  block: Make scsi_req_init() calls implicit
  scsi: Change argument type of scsi_req_init()
  scsi: Only add commands to the device command list if required by the
    LLD
  scsi: Move most of scsi_init_command() into scsi_initialize_rq()
  scsi: Inline scsi_init_command()
  scsi: Move sense buffer pointer initialization into
    scsi_initialize_rq()
  scsi: Make scsi_initialize_rq() zero the entire struct scsi_cmnd
  scsi: storvsc: Initialize driver-private command before using it
  scsi-mq: Make behavior scsi_mq_prep_fn() closer to that of
    scsi_prep_fn()
  scsi: Consolidate more initialization code
  scsi_setup_fs_cmnd(): Call scsi_req_init() instead of open-coding it
