do all kobjects in a kset need to be the same ktype?
in the current version of the header file kobject.h, there's this comment: /** * struct kset - a set of kobjects of a specific type, belonging to a specific subsystem. * * A kset defines a group of kobjects. They can be individually * different "types" but overall these kobjects all want to be grouped * together and operated on in the same manner. ksets are used to * define the attribute callbacks and other common events that happen to * a kobject. ... snip ... that seems contradictory. the first line suggests that all the kobjects in a kset are of a specific type, yet that comment goes on to suggest that they can be "individually" different types. can someone clarify this? rday p.s. and i'm thinking that the reference to a "subsystem" could be amended since actual subsystems don't exist anymore. i may have another question about that shortly. -- ======================================================================== Robert P.

Yes.

Yes.
can someone clarify this?
Have you read Documentation/kobjects.txt first?

No, we use "subsystem" to define either a bus or class as they are the same thing in the end. thanks, greg k-h
