+Subject: [PATCH] Suppress sign-conversion warning only for ioctl calls
+
+Add targeted #pragma directives to suppress -Wsign-conversion warnings
+only around specific ioctl() calls where musl's unsigned long macros
+are converted to int. This preserves the warning for the rest of the
+codebase where it can catch real bugs.
+
+The ioctl macro/function signature mismatch is a known harmless
+difference between glibc and musl - the bit pattern is preserved.
