Sure, we can define in that way.

Sounds fine to me. You did not try to compile your patch, right? :)

block/blk-sysfs.c: In function ‘blk_register_queue’:
block/blk-sysfs.c:436: error: implicit declaration of function ‘kobj_set_name’

drivers/base/driver.c: In function ‘driver_add_kobj’:
drivers/base/driver.c:149: error: too many arguments to function ‘kobject_add’

Documentation/kobject.txt would also need an update then.

Thanks,
Kay
