Thanks for trying to bisect the root cause to earlier commit than 0af8489b0216f, as we discussed. Here I strongly suspect it's also earlier than this commit. Because the code changed here is only used with SLUB_DEBUG, which is not enabled in your config. Only later in 0af8489b0216f it becomes used also by SLUB_TINY.
