You need every socket to close and all routes to go away including the

Andrew,
This is a resend of the patch I had sent earlier at:
http://marc.info/?l=linux-kernelm=119065506607858
This patch enables group cpu scheduler feature to work with control
groups.
Could you include this in -mm for folks to test it?

Sounds like a module utilities problem since unloading one module doesn't
normally unload others.
I have to disagree here - 'modprobe -r' is specifically unloading all
modules the
specified one references as long as they have a use count of zero. The
difference to other networking modules

Hello all,
I have random hangs on kernel boot or after few minutes on a NatSemi Geode
GX1 based PC-104 (from Advantech) using kernel 2.6.23-rc6. The system locks,
no way to use SysRq key, no usefull logs.

Well it's not my call, just seems like a really bad idea to change the
error value. You can't claim full coverage for such testing anyway, it's
one of those things that people will complain about two releases later
saying it broke app foo.
Strange since we've spent years changing error values
I have small code
#include stdio.h
#include string.h
int main()
{
float f= 1256.35;
char ch[4];
printf(\n1. f : %f,f);
memset(ch,'\0',strlen(ch) );
printf(\n2. f : %f,f);
return 0;
}
Expected output is
1. f : 1256.35
2. f : 1256.35
But I am getting the output
(on windows)
1. f : 1256.35

- The scheduler devel tree has been restored
- The driver tree is presently busted, so I reverted it to the 2..23-rc8-mm1
version.

This is not a kernel problem. (Read your C book and/or ask in
a C newsgroup.)

Can't work. ch[]'s content is undefined, so strlen(ch) may read anywhere
in memory, and/or memset() write anywhere.

strlen() applied to uninitialized array = undefined behaviour.
