Pointers to contiguous pages

["Luciano A. Stertz" <luciano@xxxxxxxxxxxx>]

	I need to allocate multiple contiguous pages, so I called alloc_pages 
with the desired order of pages. I'll fill these pages with data and 
need to add them to the page cache. So I need individual pointers to 
each page contained in the buffer. How do I get them?
	Is the following code correct?

	unsigned long pfn;
	struct page *page = alloc_pages(mask, order);
	if (!page)
		return;

	/* Fill the pages... */

	pfn = page_to_pfn(page)
	for (i=0; i<(1<<order); i++, pfn++)
	{
		struct page *p = pfn_to_page(pfn);
		...
	}

	Is this correct? Is there a better way to do this?

	Thanks in advance,
		Luciano
