Yes it looks like it doesn't actually make a difference due to

do_io_submit() iterated over the userspace iocb structure pointers using
a variable i of type 'int'. This was wrong since 'nr', the number of
iocb structure pointers, could potentially be up to LONG_MAX /
sizeof(struct iocb *). Fix it (and also remove the unnecessary
initialization to 0).
