Subject: Re: [PATCH v3 0/9] Add a new LOOP_SET_FD_AND_STATUS ioctl

I've just been looking over the loop driver for other reasons,
and noticed that setting the block size still isn't possible
with LOOP_SET_FD_AND_STATUS as far as I can tell.  Might that
be worth it?  Also maybe an explicit direct I/O flag, and maybe
enough padding with a future proof flags bitmap that we can easily
extend it for new features if they pop up?
