asr(4) - camcontrol(8) reports incorrect dev_openings on 7.2-RELEASE-p3

[Glen Barber]

Hello list

Following up on a post from April [1] regarding a Supermicro server
with an Adaptec 2010S raid controller with two mirrored disks, on
7.1-RELEASE, the output of 'camcontrol tags da0' listed:

     (pass0:asr0:0:0:0): dev_openings  1

Prior to that post, there was a 'HEADS UP' post [2] noting a
regression in the CAM subsystem.  The 'HEADS UP' post announced the
regression was fixed with HEAD (8-CURRENT) r188570 and would be MFC'd
to 7-STABLE [3].

Today, I upgraded one of these machines from 7.1-RELEASE-p4 to
7.2-RELEASE-p3, and camcontrol(8) still reports the output above.  I
found a USENET post [4] from early August reporting the same behavior
on 8.0-BETA2.

Is this behavior in fact a continued regression?

Is manually setting the number of tags with -N the only workaround?

Thanks in advance.
