The 'proc_name' entry in sysfs for hisi_sas is 'null' now becuase it is
not initialized in scsi_host_template. It looks like:
[root@localhost ~]# cat /sys/class/scsi_host/host2/proc_name
(null)
hmmm.. it would be good to tell us what this buys us, apart from the
proc_name file.
I mean, if we had the sht show_info method implemented, then it could be
useful (which is even marked as obsolete now).
Thanks,
John
While the other driver's entry looks like:
linux-vnMQMU:~ # cat /sys/class/scsi_host/host0/proc_name
megaraid_sas
