Hi Martin, The patches in this series address SCSI device blocking and unblocking and fix a boot failure. Please consider these patches for kernel version v5.4. Thanks, Bart. Changes compared to v1: - As requested by James, dropped the patch that changes the return type of scsi_target_block() and moved the WARN_ONCE() statement into device_block().
