Does the slab (Maybe in debug mode) stumps over some of the record memory? If the memory is constant what is then the difference between the two cases? > Certainly it's simple enough to reinitialize the work every time we > allocate an inode here, but I don't think this is really a rpc_pipefs > bug per-se. That depends on the API intention. If an init is intended after SLAB free then yes if not then not. We should ask for the intention of this API. > I can send a patch that works around this problem, but > if there are plans to fix this in the debugobjects code, I won't > bother... > You mean other fix then calling INIT_DELAYED_WORK? is that so bad that we need more code to avoid it?
