Is it possible to use the linkage that is in the scsi_device directory of the disk that is sending the event to find the relevant block devices? For example, /sys/class/scsi_device/0:0:0:0/device/block:sda on my system tells me which block devices belong to this device. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
