Nothing to do with the 200% revenue increase it will give you? It seemed
ironic, seeing the complaint by you about Red Hat and SuSE trying to
manipulate the kernel to their own commercial ends...

Who will be going without journalling? If anyone wants/needs ReiserFS
support, they are free to patch it in. I'd be rather reluctant to, since
the only ReiserFS user I know personally lost the entire partition...

How is this relevant to the 2.4 discussion?

You want to merge the current codebase into 2.4, but you claim 2.5 is too
early for a merge?

Again, how is this relevant? You have a chunk of code you want included in
the kernel during a code freeze. Either it does get included, or it
doesn't. The improvements planned for the 2.7 kernel - which could be 4
years away - aren't really relevant to this.
