NAK. Its easier to simply not allow !CONFIG_SLUB_DEBUG for cgroups based configs because in that case you certainly have enough memory to include the runtime debug code as well as the extended counters.

FWIW, I ran into issues with a combination of KASAN+CONFIG_SLUB without having CONFIG_SLUB_DEBUG, because KASAN was using functions that were broken without CONFIG_SLUB_DEBUG, so while you're at it with creating dependencies, you might want to also say KASAN+CONFIG_SLUB ==> CONFIG_SLUB_DEBUG.
