Hi list, I read that the kernel does not differentiate between threads and processes. That means, we can say that on a Linux system, the threading is purely provided by user level thread libraries, right? So as long as relevant system calls do not change, it should be possible to run any threading library on any kernel? NPTL on 2.4? pthreads on 2.6?
