So the rumor goes. I guess you are talking about a kernel version of the code. I did the original port of the user space version of the code; the patches are still up on freebsd.org. The kernel stuff is harder and easier. I know this seems at first to be contradictory... ;^). Basically, there's NetBSD code for this, and porting NetBSD code to FreeBSD is mostly what I would call "grunt work": not a lot of thinking is required. It's harder, because as FreeBSD changes it's VM system, it becomes harder to keep a lot of things up to date (file systems, etc.). Erez Zadok's code for FiST (Filesystem Stacking Templates) used to work with 4.3, but the changes to 4.5 were significant enough that cache coherency was broken. In any case, it's not like an obscene amount of work had to have been invested by Scott Long to make the thing work, so duplicating it is not tantamount to searching for The Rosetta Stone. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
