__do_page_cache_readahead	__do_page_cache_readahead() actually reads a chunk of disk. It allocates* the pages first, then submits them for I/O. This avoids the very bad* behaviour which would occur if page allocations are causing VM writeback.
swap_cluster_readahead	swap_cluster_readahead - swap in pages in hope we need them soon@entry: swap entry of this memory@gfp_mask: memory allocation flags@vmf: fault information Returns the struct page for entry and addr, after queueing swapin.
swap_vma_readahead	swap_vma_readahead - swap in pages in hope we need them soon@entry: swap entry of this memory@gfp_mask: memory allocation flags@vmf: fault information Returns the struct page for entry and addr, after queueing swapin.* Primitive swap readahead code
