I was thinking more in terms of device driver information. All of the "how to write a driver for newbus", "how to write a CAM driver", "how to use devfs from the kernel", "what XXX to do in FreeBSD, given YYY in Linux", "how to port a driver from Linux to FreeBSD", etc., are missing. While it's true that kernel locks and mutexes are documented for SMPng, he posted to -hackers, not -current, and so he's probably not interested in -current primitives that aren't available in the 4.x -RELEASE and -STABLE branches. His points about the handbook are salient, too. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
