+Subject: [PATCH] liburing.map: Export
+ `io_uring_{enable_rings,register_restrictions}`
+
+When adding these two functions, Stefano didn't add
+io_uring_enable_rings() and io_uring_register_restrictions() to
+liburing.map. It causes a linking problem. Add them to liburing.map.
+
+This issue hits liburing 2.0 to 2.3.
+
+[flow: backport to liburing 2.3]
