Hello Quinn and Himanshu,
The above information is not only useful to people who are debugging the
QLogic target driver but also to end users who want to check which
initiator ports have already logged in to a target port. Hence my
proposal to move this information from debugfs to another location (e.g.
configfs or sysfs). Users of other target drivers are probably also
interested in seeing which sessions are active. How about adding the
functionality for reporting session information per target port in the
LIO core in such a way that some attributes are available for all target
drivers (e.g. initiator port name, SCSI command statistics) and such
that target drivers can define additional attributes to exported for
each session (e.g. port ID, handle, ...).
Thanks,
Bart.
