Define KASAN_GRANULE_PAGE as (KASAN_GRANULE_SIZE << PAGE_SHIFT), which is the same as (KASAN_GRANULE_SIZE * PAGE_SIZE), and use it across KASAN code to simplify it.What's the physical sense behind KASAN_GRANULE_PAGE? Is it something more than just a product of two constants?No, just a product.quoted
The name suggests it might be something page-sized, but in reality it is not.What name would you prefer?
Is it actually KASAN_GRANULES_PER_SHADOW_PAGE ? AFAIK we're trying to calculate the granules that we can fit into a page of shadow memory. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
