Okay, I'm in the middle of developing a pseudo device driver under 2.2.18. Processes that use it generally mmap() it, and in the mmap handler, it sets up a nopage handler. Here's the question: After the nopage handler has been called and pages have been mapped to client processes' spaces, how can I "unmap" certain pages from processes that memory has been mapped to, say from the ioctl handler? If not unmap, then at least create a condition where the nopage handler would have to be called again for particular pages.. Any help would be appreciated. Thanks, John Jordan PS- I did look briefly through the list archives but couldn't find anything.. and this is my first post to the list; if I sound like an idiot, well.. it's to be expected. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
