I did not find any users passing '1' to sas_queue_reset() in the git
history. It seems it is never used. So It's ok to remove it, I guess.

Just one nit, there should be a blank between "scsi:" and "libsas" in
the subject:

scsi: libsas: Simplify sas_queue_reset and remove unused code

Otherwise looks good to me:

Yeah, code wise, it looks good.
However, I am seeing issues with completions for commands that use command
duration limits. There are some unusual completions that needs special handling
with CDL (e.g. some aborted commands can be notified with a success and
sense-data-available-bit set. For these, we kick libata-EH but it seems that
this is not well working with libsas. So I wonder if this code may need to be
used for CDL... So let's please hold on before applying this. Let me check the
CDL issues I am seeing first.


Sure. It's just a cleanup. Let's hold on until it is confirmed.

Thanks,
Jason
