I guess glibc and others only check the main version so I can write anythin in there as long as it starts with 2.6.18-, right?

I don't analyse the mainline Linux kernel periodically to see what developers with an <at> openvz.org email address have been contributing so I don't have any figures for you... but Parallels (the company that sponsors OpenVZ from their Virtuozzo product) has shown up as a top company (in the top 12) and one of their developers has also been in the top 15 of individual contributors to the mainline kernel on a few releases. So generally speaking, they are big contributors to the mainline kernel. containers are really the combination of many different features in many different subsytems in the kernel so it may not be obvious that all of the work they contribute is directly related to containers or LXC. For example, here are some contributions from the last few weeks: http://lwn.net/Articles/375565/ http://lwn.net/Articles/373994/ http://lwn.net/Articles/374547/ http://lwn.net/Articles/373513/ So far as real stats, some time ago I had an email conversation with Kir Kolyshkin who is the OpenVZ Project manager and I asked how to find out what OpenVZ has contributed and he gave me some commandline tips... that I must admit I haven't followed through on. The figures he shows in his examples are dated but you get the idea. Here's the quote:(Continue reading)

Just right now I've updated the OpenVz wiki graph that illustrates the number of patches from OpenVZ developers were merged into mainstream Linux kernel.
