The link is rather old indeed. I have been searching the people who are busy now implementing IEEE 1003.1b now for a long time, but can't seem to find the right persons. I they read this, please mail me.
I want to help implement RT timers! (have applied the patch mentioned in the document above on a 2.2.5 kernel, but it is difficult to find out what things have already been provided in the kernel or in libc! I finally made my own lib and header file to test the thing)
Thx.
