tested it too, running linux 2.6.23 in a qemu instance, and the patch
worked. But i would prefer to take the try_module_get() stuff into
pkt_setup_dev() because it is used also in the older procfs interface.
Can we run into the same problem here, means procfs holds no module
references too, like sysfs now?
The procfs interface can only be used to get some debug data out from the
driver, not to bind the driver to a CD/DVD device, so it shouldn't be a
problem.
The other way to bind a device is to use the pktsetup program, which is
doing ioctl calls to the driver. In that case, user space has to open the
device before being able to do the ioctls, and the open call will increase
the reference count.
