You can certainly put the payload into multiple lists. From http://www.crashcourse.ca/introduction-linux-kernel-programming/intermission-lets-talk-about-linked-lists-and-containerof-free http://www.crashcourse.ca/introduction-linux-kernel-programm...: > More to the point, a payload is welcome to participate on several lists, but only after defining an internal list_head object for each list. In other words, unlike the payloads you're used to that contain only pure data and could (theoretically) be on an infinite number of lists at once, objects on kernel lists can be only on those lists for which they have an internal set of links. It's an interesting way to lock down what lists you're willing to be a member of.
