Pat, I need your help tracking this one down... :-)
Your recent patch creating find_bus("scsi") always returns NULL. I see that's because bus_subsys.list is empty. Now, why is it empty, when the SCSI driver did a bus_register()? It comes down to the code in kobject_add(), where struct subsystem *s = kobj->subsys == NULL, thus the list_add_tail code never gets called in there.
The calls go something like this:
scsi_sysfs_register() bus_register(&scsi_bus_type) subsystem_register(scsi_bus_type->subsys) subsystem_init() kobject_init() sets kobj->subsys = subsys_get(kobj->subsys) which seems wrong kobject_register() kobject_add() where kobject->subsys is NULL
Strange, but true, and it may be kobject_init() that's borked setting kobj->subsys.
Please advise.
Thanks, Matt
