jhb 3fab33edd0 The changes that introduced fo_mmap() treated all character device ... mappings as if MAP_SHARED was always present since in general MAP_PRIVATE is not permitted for character devices. However, there is one exception in that MAP_PRIVATE mappings are permitted for /dev/zero. Only require a writable file descriptor (FWRITE) for shared, writable mappings of character devices. vm_mmap_cdev() will reject any private mappings for other devices.
