scsi_unregister_driver in 2.6.10

scsi_unregister_driver in 2.6.10

[Vivek Mahajan]

I was working on my SCSI module and tried to use
scsi_unregister_driver(). But looks like it has been made GPL only. I
get unresolved symbol : driver_unregister(), when I tried to load the
module. I think it is #defined to driver_unregister() in
include/scsi/scsi_driver.h. And driver_unregister is exported as GPL
only.

At the same time, scsi_register_driver() works with non GPL code
without any problem. As this call is exclusively defined in
drivers/scsi/scsi_sysfs.c.

I was just wondering wss it unintentional Or there was a purpose
behind that to make scsi_register_driver( ) as non GPL and
scsi_unregister_driver( ) as GPL only.

Any help in this matter will be highly appreciated.

Regards,
Vivek

I think this was unintentional.  However, I'm not sure there's a
compelling reason to undo it -- scsi_register_driver is for registering
top-level drivers like st, sr, sd and osst.  What kind of driver is this
that you're writing?

Thanks for ur reply back. The driver is an iSCSI driver which does
registeration with scsi generic driver for the various SATA drives. In
2.4 we used to use scsi_register_module() which is gone in 2.6.

It is a non GPL driver and I was just wondering what would be the work around.

Thanks muchly for your help.
