I'd like to implement simple and fast redirection engine by implementing userspace module (or even kernel trusted module but I don't know how to do it - any docs or examples???) and I've some questions about userspace architecture.When I ran ps -axf I get: 3474 pts/0 S 0:00 [TUX date] 3476 ? Ss 0:00 [TUX manager] 3477 ? S 0:00 \_ [TUX worker 0] 3478 ? S 0:00 \_ [TUX worker 0] 3479 ? S 0:00 \_ [TUX worker 0] ... (64 x TUX worker 0) 3475 ? S 0:00 [TUX logger]It suggests that multiple TUX worker processes (or threads) are handling requests from kernel. Is it true? I need to know if my userspace module run inside one process in one thread or can be run in multiple threads or even processes.
OK - I've read carefully the kernel patch and I've found that those threads are cachemiss IO threads.
As far as I understand TUX manager is spawning separate TUXTHREADS "TUX worker" processes which handles user modules. Each "TUX worker" thread has corresponding NR_IO_THREADS cachemiss kernel threads. There is also one TUX logger kernel thread that is started in kernel and one "TUX date" process started by userspace tools.
