+ * @page page_linux_explicit_synchronization_unstable_v1 The linux_explicit_synchronization_unstable_v1 protocol
+ * Protocol for explicit synchronization
+ *
+ * @section page_desc_linux_explicit_synchronization_unstable_v1 Description
+ *
+ * This protocol specifies a set of interfaces used to provide explicit
+ * synchronization of buffers to the the client.
+ *
+ * Warning! The protocol described in this file is experimental and backward
+ * incompatible changes may be made. Backward compatible changes may be added
+ * together with the corresponding interface version bump. Backward
+ * incompatible changes are done by bumping the version number in the protocol
+ * and interface names and resetting the interface version. Once the protocol
+ * is to be declared stable, the version number in the protocol is removed and
+ * the interface version number is reset.
