Hi All, I understand that PG_locked flag is set in page->flags before initiating I/O on a page to avoid parallel I/Os. But I am wondering how we avoid other processes and threads from accessing the same page in userspace if it is mapped(MAP_SHARED) to the address space of multiple processes. Could somebody please throw some light on this. Thanks & Regards, Arvind. __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security.
