Hugh Dickins abab053427 shmem: cleanup shmem_add_to_page_cache ... shmem_add_to_page_cache() has three callsites, but only one of them wants the radix_tree_preload() (an exceptional entry guarantees that the radix tree node is present in the other cases), and only that site can achieve mem_cgroup_uncharge_cache_page() (PageSwapCache makes it a no-op in the other cases). We did it this way originally to reflect add_to_page_cache_locked(); but it's confusing now, so move the radix_tree preloading and mem_cgroup uncharging to that one caller.
