Why do we give a locked page a special consideration? this is really new stuff.... okay, wp should be "write protect", right? if that so, I have a mild good guess that copying the page is actually a way to not add another pressure to the locked page. By doing that, write protect could be done right away and write operations follow that. Not sure if we need to do synchronization between the new page and the old locked page. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
