Regular files shouldn't be returning EIO and don't in my tests. The file systems manage direct I/O EOF handling in their own block or direct_IO callbacks. Block devices do not and instead do the size checks up front. Raw devices were bypassing the block device check, so only the raw driver should be having this issue.
