Yes, thanks.  

Perhaps in Documentation/ABI/testing/sysfs-bus-scsi-devices-hpsa
(which doesn't exist) and/or in Documentation/scsi/hpsa.txt (which does exist, and
is where other hpsa specific sysfs attributes are documented.)  Probably so
as not to duplicate things, the latter.  Or maybe what documentation of
sysfs things that is currently in hpsa.txt should be moved to Documentation/ABI/...
and a reference to it put in hpsa.txt?
