The logical unit information is missing from the UFS command tracing
output. Although the device name is logged, e.g. 13200000.ufs, this name
does not include logical unit information. Hence this patch that replaces
the device name with the SCSI ID in the tracing output. An example of
tracing output with this patch applied:
