+Subject: [PATCH] batctl: Work around uclibc collision for __unused
+
+uclibc on 64 bit systems uses struct members called __unused. These
+conflict with the definition of __unused in batctl. Such a conflict results
+in a build error because the struct member will be replaced with the
+__attribute__((unused)).
+
+This can be avoided by renaming it to the Linux kernel name
+"__maybe_unused".
