Yeah, I've been off-and-on working on getting the kernelspace code to work, basing it off of the Digital Unix code, the closest VFS layer. The problem that's been keeping me from doing much more is lack of understanding the buffer cache, which is completely different from the Digital Unix buffer cache. I should probably make what code I do have up on the web. No, I haven't tested it. Rob is right, though, that the priority should be getting a working server before getting a "real" client. However, given the sheer ammount of stuff that OpenAFS does in kernelspace rather than userland, I'm not sure that the server doesn't depend on the kernel module. -- Tom Maher To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-afs" in the body of the message
