Donenfeld commit 5eee7bd7e245914e4e050c413dfe864e31805207 upstream. This worked before, because we made all callers name their next pointer "next". But in trying to be more "drop-in" ready, the silliness here is revealed. This commit fixes the problem by making the macro argument and the member use different names. Signed-off-by: Jason A.
