A little digging brings us to: 056c62418cc639bf2fe962c6a6ee56054b838bc7 which seems to have introduced that. > It seems that this has to be especially applied to > regular slab caches because those are the ones that mostly have off slab > structures. So modify init_lock_keys to run over all slab caches? That sounds about right, worth a try. Also over new caches, the above reverenced commit removes a hook from kmem_cache_init() which we really need I suppose. I'll try and compose a patch if nobody beats me to it, but need to run an errand first. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
