Rob Pike should read about D-Bus in the kernel[1], next. Maybe he'll have some comments. No, I mispoke, I think he'll definitely have some comments. [1] http:/

  There is a legitimate debate about the performance vs. elegance tradeoff that sendfile represents. Putting D-Bus in the kernel is just a bad idea.

    I disagree. I think it's nothing but a good idea compared to its current state, for the following reasons: - IPC in userspace is insecure, and currently easily subverted by rootkits. - When a system is under heavy load, the dbus daemon becomes a choke point for scheduling. "Spammy" processes can prevent messages from reaching higher priority processes. - It is a lifesaver for embedded devices with poor multitasking capabilities. Think about ucLinux. - It's not for everyone. It's like PF_RING for packet capturing. - It makes sense not only for performance, but also reliability. - Even though DBus can be improved in several other aspects, I think it's nice that someone sat down and wrote this instead of bikeshedding on some website. 2c
