Ryusuke Konishi bf585ee198 nilfs2: reject invalid file types when reading inodes ... commit 4aead50caf upstream. To prevent inodes with invalid file types from tripping through the vfs and causing malfunctions or assertion failures, add a missing sanity check when reading an inode from a block device. If the file type is not valid, treat it as a filesystem error.
