+From d4714fd7aac9c5f499c406703bc437dc6cf72ef3 Mon Sep 17 00:00:00 2001
+From: Steffen <steffen.winter@proton.me>

+Subject: [PATCH 1/3] Add custom error function for tests.
+
+On musl systems, liburing cannot build examples and tests due to
+it's usage of error.h. t_error calls fprintf(stderr, ...) and
+exits.
+
+Closes: #786
