[SCSI] sg: fix device number in blktrace data
Hi,
we have run into an issue with blktrace being started for sg devices.
Please apply.
Thanks,
Martin
From: Martin Peschke <mpeschke@linux.vnet.ibm.com>
The device number denoting a generic SCSI devices (sg) in a blktrace
trace is broken; major and minor are always 0. It looks like
sdp->device->sdev_gendev.devt is not initialized properly.
The fix below uses other data to make up a valid device number,
similar to the way an sg device number is generated for sysfs output.
