While debugging I've noticed that __copy_to_user() fails when I stop the Bottom Half before the call to __copy_to_user(), so if the page in not currently mapped then it forbids do_page_fault() to get invoked and hence the failure. So I would like to know whether this hypothesis is right or not? And if not then the possible explanation. Thankx Prasenjit __________________________________________________ Do You Yahoo!?
