2024 +0200 iov_iter: don't require contiguous pages in iov_iter_extract_bvec_pages The iov_iter_extract_pages interface allows to return physically discontiguous pages, as long as all but the first and last page in the array are page aligned and page size. Rewrite iov_iter_extract_bvec_pages to take advantage of that instead of only returning ranges of physically contiguous pages.
