In current implementation, the option "LVM_TEST_BACKING_DEVICE" only supports to specify one backing device; this patch is to extend the option to support multiple backing devices by using comma as separator, e.g. below command specifies two backing devices: make check_lvmlockd_idm LVM_TEST_BACKING_DEVICE=/dev/sdj3,/dev/sdk3 This can allow the testing works on multiple drives and verify the locking scheme if can work as expected for multiple drives case. For example, for Seagate IDM locking scheme, if a VG uses two PVs, every PV is resident on a drive, thus the locking operations will be sent to two drives respectively; so the extension for "LVM_TEST_BACKING_DEVICE" can help to verify different drive configurations for locking.
