With CONFIG_DEBUG_KOBJECT_RELEASE=y, removing and immediately reloading the dmi-sysfs module causes the following warning: sysfs: cannot create duplicate filename '/firmware/dmi' kobject_add_internal failed for dmi with -EEXIST, don't try to register things with the same name in the same directory. The "dmi" directory stays in sysfs until the dmi_kobj is released, and DEBUG_KOBJECT_RELEASE delays that. I don't think we can hit this problem in normal usage because dmi_kobj is static and nothing outside dmi-sysfs can get a reference to it, so the only way to delay the "dmi" release is with DEBUG_KOBJECT_RELEASE.
