> We always switch off the debugging bits of slabs that are too large
> for free pointer relocationi (256k, 512k). This means that we may create
> kmem_cache structures that look as if they are satisfying the requirements
> for merging even if slub_debug is set. Sysfs handling may think they are
> mergeable and thus creates unique ids that may then clash.
