maximum number of process in linux with paging

Question

I heard that maximum number of process(tasks) in linux is calculated with

"number of threads = total virtual memory / (stack size*1024*1024)"

however, I am curious that since page tables can not be paged out

and every process needs it's own page tables(including page directory)

I think this can be a factor to limit number of process in OS.

am I correct or wrong?

根据《 IA-64 Linux内核：设计与实现》一书的第4.3章“页表” ，您是正确的。
