Hi Rik,
I can't reproduce it on my box.
Could you provide a "lvcreate -d" output of what you did to help
me to dig into that one.
Did somebody else out there face the same 0.8final snapshot weirdness?
Yes. I have

My question from above is: how can the via audio mmap in test10-preXX
be improved by using kiobufs? I am not a kiobuf expert, but AFAICS a
non-kiobuf implementation is better for audio drivers. (and the via

Actually, you don't have to change every makefile, because

I'd rather see "Rules.make" just base itself entirely off the new-style
Makefiles, and have it use "$(obj-y)" instead of O_OBJS etc.
Then, _old_style Makefiles could be fixed up by doing a

As is being discussed here, C99 has some replacements to the gcc syntax
the kernel uses. I believe the C99 syntax will win in the near future,

It includes Nils' 2.2 changes, use of initcalls (so compiled-in

This may be, as you say, "harmless". It is, however, a bug. The

No. It is not. The module usage count doesn't have a direct relation
to the number of open devices.
