Changes

This graph shows how many patches from OpenVZ developers are were merged in into mainstreamLinux kernel, for per each kernel version.

It is done in drawn by gnuplot. Data using the data set produced by a simple shell script working on obtained from kernel git repository.

Here is the script to produce the data for the graph, called <code>count</code>:
