The rename is to support different use case as mentioned below in patch 14: "Depending on different use cases, callers expecting to deal with va, page or both va and page for them may call page_frag_alloc_va*, page_frag_alloc_pg*, or page_frag_alloc* API accordingly." Naming is hard anyway, I am open to better API naming for the above use cases. > > . >
