From: "tang.junhui" <tang.junhui@xxxxxxxxxx>
Environment variables such as DM_TABLE_STATE are used in kpartx.rules which exported
by "dmsetup export" in previous udev rules in SuSE OS, however, there is no such command
"dmsetup export" in redhat OS, so these environment variables are not initialized and
partitions cannot be created. This patch replace "dmsetup export" with "dmsetup info"
to get the status of mapped device, which can work well both in SuSE and redhat OS.
