[PATCH v3 00/12] SCSI patches for kernel v4.13

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

Hello Martin,

This patch series consists of the bug fixes and improvements I came up with
during the past two months. This patch series has been developed on top of
your 4.13/scsi-queue branch. Please consider these patches for kernel v4.13.

Thanks,

Bart.

The changes compared to v2 of this patch series are:
- Addressed Christoph's review comments: added an explanation to patch
  "Protect SCSI device state changes with a mutex" of why that change is
  needed. Removed a printk() from patch "Make __scsi_remove_device go
  straight from BLOCKED to DEL". For scsi-mq, moved the initialization of
  .prot_sdb from scsi_mq_prep_fn() into scsi_init_request(). Fixed the
  driver name in the virtio_scsi patch.

Between v1 and v2:
- Left out the block layer patches from this series.
- Reworked this patch series such that it applies cleanly on the 4.13 SCSI
  patch queue and no longer depends on any block layer changes that are not
  yet upstream.
- In patch "Avoid that scsi_exit_rq() triggers a use-after-free", make the
  prep functions save and restore the SCMD_UNCHECKED_ISA_DMA flag.
- Added patch "Introduce scsi_start_queue()".
