+Subject: [PATCH] test: Fix error factory test for musl libc compatibility
+
+It uses errno value 123456 in test handling of unknown errors. This works
+on glibc which accepts any errno value, but musl libc validates
+errno ranges more strictly (typically 1-133).
+
+Ignore test on non-glibc systems
+
+Upstream-Status: Pending
