Xiongwei Song 16f2ef98cc floppy: Add max size check for user space request ... [ Upstream commit 545a32498c536ee152331cd2e7d2416aa0f20e01 ] We need to check the max request size that is from user space before allocating pages. If the request size exceeds the limit, return -EINVAL. This check can avoid the warning below from page allocator.
