Helper bpg_msg_pull_data() can allocate multiple pages while linearizing multiple scatterlist elements into one shared page. However, if the shared page has size > PAGE_SIZE, using copy_page_to_iter() causes below warning. e.g. [ 6367.019832] WARNING: CPU: 2 PID: 7410 at lib/iov_iter.c:825 page_copy_sane.part.8+0x0/0x8 To avoid above warning, use __GFP_COMP while allocating multiple contiguous pages.
