This device is a block device that allows a user to effectively treat an Inode as a block device. The static construction method is given an OpenFileDescription reference but validates that: - The description has a valid custody (so it's not some arbitrary file). Failing this requirement will yield EINVAL. - The description custody points to an Inode which is a regular file, as we only support (seekable) regular files. Failing this requirement will yield ENOTSUP. LoopDevice can be used to mount a regular file on the filesystem like other supported types of (physical) block devices.
