James,
It appears there is a missing class_device_del.
The comments for transport_remove_device indicate
that transport_remove_classdev should call it
(which the attached patch does), but the comment in
attribute_container_remove_device:
If you want a
* two phase release: remove from visibility and then delete the
* device, then you should use this routine with a fn that calls
* class_device_del() and then use
* attribute_container_device_trigger() to do the final put on the
* classdev.
Indicate that maybe transport_destroy_classdev and
transport_remove_device are incorrect. However,
attribute_container_remove_device will do a
list_del(&ic->node); so that later calls to
attribute_container_device_trigger would not be able
to do the final put on that classdev. I assumed the
comments in attribute_container_remove_device
are incorrect, so the attached patch made against
scsi-rc-fixes-2.6 adds a call to class_device_del
to transport_remove_classdev.
I did not fix the comments in attribute_container_remove_device
becuase I was not 100% certain what is the correct behavior or
usage.
