+# @x-nbd-server-add-bitmap:
+#
+# Expose a dirty bitmap associated with the selected export. The bitmap search
+# starts at the device attached to the export, and includes all backing files.
+# The exported bitmap is then locked until the NBD export is removed.
+#
+# @name: Export name.
+#
+# @bitmap: Bitmap name to search for.
+#
+# @bitmap-export-name: How the bitmap will be seen by nbd clients
+#                      (default @bitmap)
+#
+# Note: the client must use NBD_OPT_SET_META_CONTEXT with a query of
+# "qemu:dirty-bitmap:NAME" (where NAME matches @bitmap-export-name) to access
+# the exposed bitmap.
+#
+# Since: 3.0
