A change in the letter represents a major change to the patch, and the numbers represent bugfixes within an iteration. Ingo issues a patch, people report any problems or latency issues, and based on this feedback he posts a new one. For example the -L series moves all hardirq processing to the irqd thread. I had to hack the kernel source to make the soundcard and RTC interrupts 'direct'. In the -M series this can all be done via /proc. There is not really any point in using anything but the latest version, because the patches are improving every day. Lee
