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()".
