James,
Careful with the spin:-) It is arguable which one is
redundant. I am testing this patch and it breaks
lsscsi and sg_map26 (again). Could you tell me which
version of the lk 2.6 series the scsi_generic:sg<n>
link appeared in? Because if I switch my code to
search for a scsi_generic:sg<n> symlink rather than
following the generic symlink then I will break
backward compatibility prior to that version (unless
I cope with both). At least one major distro has an
"enterprise" edition based on lk 2.6.5

I can see from my lsscsi code and the st driver that
tape devices still have a plain old "tape" symlink.
Should I be expecting that one to break in the near
future?
