Hi, I have a char driver that implements mmap by overriding the nopage vm_operation (rather than using remap_page_range). What it the correct way to invalidate these mappings so I will re-take a fault on the next access to the addresses previously mapped by my nopage function? ~mc -- Kernelnewbies: Help each other learn about the Linux kernel.
