The main question I have about these fields is what the difference is
between st_blksize and st_alloc_blksize?

I would assume that st_blksize is some ideal I/O size, not the
allocation block size.

But there are several optimal IO sizes, so unless there is a clear
description of what each of these fields is intended to be used for,
it doesn't make sense to add them in.

Dave Chinner might be able to answer better as he suggested these
I/O information fields.
