Re: [PATCH 1/4] rust: netlink: add raw netlink abstraction

...

+/// The default netlink message size.

struct sk_buff is a core data structure which appears all over the
networking stack, but also other places like crypto, scsi, tty, file
systems, etc. Since it is a top level data structure, it seems odd
Rust puts it into netlink.rs.

How do you see the Rust SkBuff evolving to a general purpose data
structure which can be used everywhere?
