The problem is that you may only have a single page table. One process with multiple threads will just fault in one thread in order to install the mapping to the page. The others threads may be running on different nodes and different processors but will not generate any faults. Pages will not be replicated as needed. The scheme only seems to be working for special cases of multiple processes mapping the same file. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
