DRM drivers share a common address_space across all character-devices of a single DRM device. This allows simple buffer eviction and mapping-control. However, DRM core currently waits for the first ->open() on any char-dev to mark the underlying inode as backing inode of the device. This delayed initialization causes ugly conditions all over the place: if (dev->dev_mapping) do_sth(); To avoid delayed initialization and to stop reusing the inode of the char-dev, we allocate an anonymous inode for each DRM device and reset filp->f_mapping to it on ->open().
