| |
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
