I'm thinking this is the warning that fired in the 0day report, but I can't double-check yet since 0day didn't upload its source tree anywhere I can check. And all the drivers I can easily test don't use drm_dev_alloc anymore ...
Also if I'm correct supreme amounts of bad luck because usually kslap (for bigger structures) gives us something quite a bit bigger than what we asked for.
