The do_div() macro now checks its arguments for the correct type, and refuses anything other than u64, so we get a warning about nbd_ioctl passing in an loff_t: drivers/block/nbd.c: In function '__nbd_ioctl': drivers/block/nbd.c:757:77: error: comparison of distinct pointer types lacks a cast [-Werror] This changes the nbd code to use div_s64() instead, which takes a signed argument.
