Description
This shows KLOC (thousands lines of code) changes in three kernels:
- OpenVZ 2.6.27-aivazovsky,Z based on vanilla 2.6.27 kernel.
- OpenVZ 2.6.18-028stab062.1, based on RHEL5 U3 kernel.
- RHEL5 U3 2.6.18-128.1.1.el5, based on vanilla 2.6.18 kernel.
Conclusions
- Even without drivers RHEL5 patches add/delete 434 KLOC, which is 8.5x times bigger then OpenVZ kernel modifications (51 KLOC);
- OpenVZ based on mainstream 2.6.27 kernel requires 40% less modifications (not counting modules) due to on going mainstream integration.
