Description

Had a compilation fail due:

directio.c: In function 'main':
directio.c:114:16: error: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type '__blksize_t' [-Werror=format=]
                st.st_blksize);
                ^

This is the code

        printf("directio on %s for %dx%lu bytes \n", fname, blocks,
               st.st_blksize);

Think we can get by with just casting that st_blksize to an unsigned long. I'll push a patch
