|The kernel debugger (kdb) is in no way required or related to xfs. It’s in cvs because it can be a very useful tool for debugging xfs problems, and there’s even an xfs debug module that adds many xfs-specific kdb commands. Also, the kdb maintainer Keith Owens works for sgi.
For the past several months, we’ve offered patches against each major 2.4 kernel, almost always available within a week of the kernel release. These patches are also split up so you can exclude kdb if you want to. It’s true that these are cvs snapshots, packaging and testing a “full release” is time consuming, so we do it only at various points in time.
We do use a different source control system inside of sgi, and export it to cvs. You don’t miss much though – per-file comments are preserved for example. We don’t often tag the cvs tree, though, it’s a bit of a pain and doesn’t offer _that_ much advantage over just checking out by date.
