+Subject: [PATCH 4/4] test-rtnl: fix -std=c23 build failure
+
+gcc-15 switched to -std=c23 by default:
+
+    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=55e3bd376b2214e200fa76d12b67ff259b06c212
+
+As a result `ell` fails the build as:
+
+      passing argument 1 of 'l_idle_oneshot' from incompatible pointer type [-Wincompatible-pointer-types]
+      501 |         l_idle_oneshot(test_next, NULL, NULL);
+          |                        ^~~~~~~~~
+          |                        |
+          |                        void (*)(void)
