From kernel version 2.6.18 onwards, however, Linux is gradually
becoming equipped with real-time capabilities,
most of which are derived from the former

patches developed by Ingo Molnar, Thomas Gleixner and others.

Until the patches have been completely merged into the
mainline kernel
(this is expected to be around kernel version 2.6.24 or 2.6.25),
(this is expected to be around kernel version 2.6.20),
they must be installed to achieve the best real-time performance.
