Re: Differences between NetBSD 3.0 and 4.0 with regard to the filesystem

I don't have time to rewrite this piece of software and I need to know what
has changed between the 3.0 and 4.0 release of NetBSD with regard to the file

Aditionally: Where is the file system locking document ?

        If you're not having any luck tracking this down otherwise you
        could always try cvs updating the tree to midway between NetBSD
        3.0 and 4.0 and testing a kernel from there with a NetBSD 3.0
        userland, and based on the results then try midway between that
        and NetBSD 3 or 4. A few iterations should hopefully allow you to
        narrow in on the specific change that affects you. Of course each
        pass may take some manual merging of your filesystems code :/

        Presumably this is purely a kernel isue - does a NetBSD 3.0
        userland on a NetBSD 4.0 kernel still panic for you?
