Hi all,
it seems the sbp2 driver module can never be unloaded because the
module "is in use" even though all SBP-2 devices were physically removed
(after umount etc.). I believe it is an old problem of the last few 2.6
kernels but am not sure when it was really introduced.
One thing can easily be spotted by "ps x": The scsi_error_handler of an
SBP-2 device does not exit. The /sys/bus/scsi/devices/$a:$b:$c:$d
vanished, the /sys/bus/ieee1394/devices/$guid-$unit too, but the
scsi_eh_# daemon is still there. It seems shost->shost_gendev.release
was never called.
So I just added a few more scsi_host_put() to sbp2_remove_device().
scsi_eh_# now goes away when I disconnect the device. Still, modprobe -r
sbp2 fails with "FATAL: Module sbp2 is in use.".
