Ah, that's what you meant. I think of things outside the source tree as external. I think of things outside the kernel as userland. So, in your terms, I mean 3rd party. > When I see "external code depending on kernel structures...", I > inevitably think of "ps" and similar code that has to be recompiled > when the kernel data structures change because some idiot thought > it's be a good idea to read the KVA space instead of implementing a > procedural interface that wouldn't change between structure revs. > ;-) Drew ------------------------------------------------------------------------------ Andrew Gallatin, Sr Systems Programmer http://www.cs.duke.edu/~gallatin Duke University Email: gallatin@cs.duke.edu Department of Computer Science Phone: (919) 660-6590 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
