In addition to these three, I see the following places that need to be changed: Documentation/gpu/drm-mm.rst:300: int (*fault)(struct vm_fault *vmf); drivers/gpu/drm/virtio/virtgpu_ttm.c:117:static int virtio_gpu_ttm_fault(struct vm_fault *vmf) - #if 0 code. convert anyway. drivers/gpu/drm/vkms/vkms_drv.h:68:int vkms_gem_fault(struct vm_fault *vmf); drivers/gpu/drm/vkms/vkms_gem.c:46:int vkms_gem_fault(struct vm_fault *vmf) fs/ext4/ext4.h:2472:extern int ext4_page_mkwrite(struct vm_fault *vmf); fs/ext4/ext4.h:2473:extern int ext4_filemap_fault(struct vm_fault *vmf); fs/ext4/inode.c:6154:int ext4_page_mkwrite(struct vm_fault *vmf) fs/ext4/inode.c:6251:int ext4_filemap_fault(struct vm_fault *vmf) fs/iomap.c:1059:int iomap_page_mkwrite(struct vm_fault *vmf, const struct iomap_ops *ops) include/linux/iomap.h:144:int iomap_page_mkwrite(struct vm_fault *vmf, const struct iomap_ops *ops); - I saw you just resent this patch. mm/filemap.c:2751:int filemap_page_mkwrite(struct vm_fault *vmf) - This is the NOMMU case, so I suspect your testing didn't catch it.
