EVPD page 0x83 is used to uniquely identify the device.
So instead of having each and every program issue a separate
SG_IO call to retrieve this information it does make far more
sense to display it in sysfs.
Christoph's suggestion of binary sysfs attributes for this rather than
the text ones you have is better ... because your current ones are going
to truncate when they run off the one page of data sysfs text attributes
get (i.e. about 2k of vpd).
Yes, I thought of that, too.
I thought to remember that binary attributes are reserved for
firmware/hardware-dependent interfaces.
If that's not the case I'll be moving to a binary attribute here.
Will be resending the patchset.
What should happen with the first patch in the series, then?
When moving to a binary attribute the first patch isn't required
anymore; should I drop it or send as a separate patch?
Cheers,
Hannes
