I disagree. My belief is that all newbus should do is to store a void * of the drivers chosing. In particular it shall not allocate storage for a softc. The contents of the softc is entirely the drivers, newbus has no business inside the softc, consequently it should not allocate it. From that point of view, my driver does the right thing. But best of all: With the function added, newbus can now support both models. This nicely represents the FreeBSD way: "We provide tools, not politics". And on that note, this particular thread is dead from my end. The other thread on which device semantics we choose for removeable devices is *far* more interesting. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD coreteam member | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
