[ltt-dev] ltt/ltt-relay-alloc.c:46: error: 'cpu' undeclared

[Pierre-Marc Fournier]

0.27 introduced major and experimental changes. I'm sure Mathieu will 
fix this as soon as he reads your post. But if you want to get running 
quickly:

- You could go back to 0.26, which was pretty stable and also applies to 
2.6.27-rc7, probably -rc8 too.
- Alternatively you could use the LTTng git repository at:

http://git.kernel.org/?p=linux/kernel/git/compudj/linux-2.6-lttng.git;a=summary

You will find the kernel tree with the patches already applied there.
