proc_name in sysfs

[Frederic TEMPORELLI <frederic.temporelli@bull.net>]

Hello,


We are using HBAs modules names from "proc_name" interface in sysfs:
/sys/class/scsi_host/hostX/proc_name.

But with new Emulex drivers (8.0.21 and +), proc_name is reporting <NULL> 
(previous drivers were reporting "lpfc").
=> In the driver code, .proc_name field from scsi_host_template structure is no 
more initialized.
James Smart told us that the "removal" of .proc_name field (not really removed, 
but no more initialized) was part of the /proc interfaces removal (suggested by 
scsi-linux feedback).

So:
1/ now, what is the aim of proc_name interface (reporting "<NULL>") in sysfs ?
2/ now, how can we get the adapter module name from sysfs ?

=> I'm just thinking that .proc_name field has to be kept initialized and/or 
something has to be changed to replace the confusing "proc" prefix.


Best regards
