I'm currently testing the Vinum/NetBSD code that the Infosys people
sent me. It's still a bit rough round the edges, but I have got to
the stage where I can build a kernel with Vinum "support" and talk to
the driver. I currently have a few questions:
1. vinum(8) has a command-line mode and uses readline for command
line editing and history. I can find the headers for readline,
but I can't find a library. What's the policy? Is readline
deprecated? I've found editline, but the interface is quite
different, and I'd prefer to keep things the same.
2. I see that direct access to bdevsw[] is no longer used. Instead,
there's the bdevsw_lookup() function. In the case of Vinum,
bdevsw accesses are either to Vinum itself, or to one of the
drives. Can I assume that the drive will not lose its bdevsw? Or
should I call bdevsw_lookup() for every I/O?
