Subject: isdisk() kludge in kernel
Cc: hackers@FreeBSD.ORG

Precedence: bulk

I was looking at isdisk and wanted to hurl chunks.

This is used by spec_open to determine if we should be allowed to open a
disk device when securelevel >= 1.

I'd like to propose changing spec_open to simply NEVER allowing the open of
a block device, or character device, if a character device has a block
device associated with it and eliminate isdisk() in kern_conf entirely.

Objections?  (p.s. I found this in 2.2.5, haven't checked 3.0 yet to see if
it was fixed, if it was, sorry for bothering you).
