Allocation of radix_tree_node objects can be easily triggered from userspace, so we should account them to memory cgroup. Besides, we need them accounted for making shadow node shrinker per memcg (see mm/workingset.c). A tricky thing about accounting radix_tree_node objects is that they are mostly allocated through radix_tree_preload(), so we can't just set SLAB_ACCOUNT for radix_tree_node_cachep - that would likely result in a lot of unrelated cgroups using objects from each other's caches. One way to overcome this would be making radix tree preloads per memcg, but that would probably look cumbersome and overcomplicated. Instead, we make radix_tree_node_alloc() first try to allocate from the cache with __GFP_ACCOUNT, no matter if the caller has preloaded or not, and only if it fails fall back on using per cpu preloads. This should make most allocations accounted.
