I got my tree working cleanly now by removing the one kfree for s->name that I missed in kmem_cache_release and by removing the refcount modifications from the last patch. I put them in a separate patch. Applying that patch causes the problem. Can you skip the last patch for now or do you want another set posted? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
