- DAX (Direct Access) is not supported on encrypted files.
+- Encrypted files cannot be used directly as swap files. To swap to
+ an encrypted file, set up a loopback device on top of it.
+ Alternatively, encrypted swap can use a dm-crypt device.

- The maximum length of an encrypted symlink is 2 bytes shorter than
the maximum length of an unencrypted symlink. For example, on an
