The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it. cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.
cdevsw_add() will print an message if the d_maj field looks bogus.
Remove nblkdev and nchrdev variables. Most places they were used
bogusly. Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.
Move bdevsw() and devsw() functions to kern/kern_conf.c
Bump __FreeBSD_version to 400006
This commit removes:
72 bogus makedev() calls
26 bogus SYSINIT functions
if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.
I4b and vinum not changed. Patches emailed to authors. LINT
probably broken until they catch up.

Announcing the Availability of the
Coda Distributed
Filesystem
for
BSD Unix Systems
Coda is a distributed file system like NFS and AFS. It is
freely available, like NFS. But it functions much like AFS in being a
"stateful" file system. Coda and AFS cache files on your local
machine to improve performance. But Coda goes a step further than AFS
by letting you access the cached files when there is no available
network, viz. disconnected laptops and network outages. In Coda, both
the client and server are outside the kernel which makes them easier
to experiment with.
To get more information on Coda, I would like to refer people to
http://www.coda.cs.cmu.edu
There is a wealth of documents, papers, and theses there. There is
also a good introduction to the Coda File System in
http://www.coda.cs.cmu.edu/ljpaper/lj.html
Coda was originally developed as an academic prototype/testbed. It is
being polished and rewritten where necessary. Coda is a work in
progress and does have bugs. It is, though, very usable. Our
interest is in making Coda available to as many people as possible and
to have Coda evolve and flourish.
The bulk of the Coda file system code supports the Coda client
program, the Coda server program and the utilities needed by both.
All these programs are unix programs and can run equally well on any
Unix platform. Our main development thrust is improving these
programs. There is a small part of Coda that deals with the kernel to
file system interface. This code is OS specific (but should not be
platform specific).
Coda is currently available for several OS's and platforms:
Freebsd-2.2.5: i386
Freebsd-2.2.6: i386
Freebsd -current: i386
linux 2.0: i386 & sparc
linux 2.1: i386 & sparc
NetBSD 1.3: i386
NetBSD -current: i386
The relevant sources, binaries, and docs can be found in
ftp://ftp.coda.cs.cmu.edu/pub/coda/
We intend to come out with new Coda releases often, not daily. We
don't want to slight any OS/platform not mentioned above. We are just
limited in our resources as to what we can support internally. We
will be happy to integrate OpenBSD support as well as other OS
support. Also, adding platform support should be relatively easy and
we can discuss this. The only difficulty is that Coda has a light weight
process package. It does some manipulations in assembler which would
have to be redone for a different platform.
There are several mailing lists @coda.cs.cmu.edu that discuss coda:
coda-announce and linux-coda. We are going to revise linux-coda to be
OS neutral, since it is mainly Coda we want to discuss. We appreciate
comments, feedback, bug reports, bug fixes, enhancements, etc.
