I feel that using these flags are not working as expected. From the
driver's prospective it should return status of the TM based on
whether it has cleared reference of the timed out IO in the driver or
not (i.e. if it is successfully able to clear the reference (i.e.
cleared from scsi lookup) of the timed out IO from driver, firmware
then return success status otherwise return failure status). It should
not check for it's above layer reference.

For an experiment, I have mocked driver to return 'task abort' with
fail status even though it was able to abort the IO. I have done this
so that we can test whether device reset is working fine or not.
I have started the IO's on a drive and using lsiutil utility I have
done link reset for that drive. Then I observe that some IO's got
timedout and received task abort TM for these timedout. As I have
hard-coded task abort TM to return with failure status, so after some
time driver has received device reset TM. after processing device TM,
in the driver still we observe that 'device_busy' value is non-zero
and driver returns this TM with failure status, even though their is
no references for the timedout IO in the driver(i.e. driver has
returned the timed out IO back to SML).
Even without modifying anything in the driver. Run the IO's on one
drive and issue device reset TM using sg_util and we observe the
device_busy for this device will be non-zero (even it has aborted all
the outstanding IOs at that time for that device) and eventually
target reset TM is received by the driver.

I have printed this 'target_busy' variable just before issuing target
reset TM to firmware and I always observe that this variable value is
zero, as shown below,
