From f8f41ae668040d58271e03bc85b58e13becb14af Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Mon, 2 Jan 2017 09:40:09 +0100 Subject: scsi: dm: Unbind all scsi based block devices before new scan New scan should unbind all block devices not to be listed again. Without this patch if scsi reset or scan is called new block devices are created which point to the same id and lun. For example: ZynqMP> scsi scan scsi_scan: if_type=2, devnum=0: sdhci@ff170000.blk, 6, 0 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 0 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 1 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 2 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 3 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 4 scanning bus for devices...
