The purpose was described here: http://article.gmane.org/gmane.linux.scsi/54155 Basically we'd like to instruct user-space to retrieve a blob of data automatically. Original implementation used the kboject hanging off the module which does not exist when CONFIG_MODULES=n. It was suggested that perhaps an alternative would be to use 'struct device' kobj. Any tips on how to trigger such a driver-specific event, perhaps a dedicated kobject exported by the driver itself??? > confused, anch'io...
