t this value over time. I also tried a similar
experiment with the e1000 driver but I couldn't get that interface to
list any errors.
I'm running these tests on FreeBSD 8.0-Beta3, but I observed the same
behaviour on FreeBSD 7.2.
Thanks

Can anyone suggest anything to try and debug/fix this problem. I'
otect claims to do what I want, but has long been missing
from FreeBSD.
In case it matters, I'm using FreeBSD 7.2, on a amd64 machine. I've
looked at HEAD and the relevant code looks the same, so I suspect I
will still have problems with that.
thanks for any help

I would also be grateful if people could point me at other examples in
the kernel where something like this is done. I have looked in quite a
few places, but I can't see why my simple app is wrong.

That way, if we are using GCC 4+ we use their __null definition,
otherwise if we are not c++ we use the standard (void *)0, and then if
we are 64bit we use 0L, and finally anything else uses 0. A quick
amd64 kernel compile seems to allow m

I think for the moment I will fix my code by not using a MTX_SPIN
(since the code is not in a interrupt), however, I think memguard
should change its lock.

Sorry no, I just ran it from a Linux host, b
Is it worth my time trying to rearrange structs? If so do you think
many of my patches would be accepted?
2) Is there a way to find out the most heavily used structs? There are
~3600 structs, and ~2000 holes, it might be a waste of my time fixing
the structs which are only used once.
thanks

Works well here, tried various combinations of the options. This is very
cool.
