I read your patch with interest, but found some trivial bad manners.

* LET_OS_MANAGE_FILESIZE is already obsoleted.
You don't have to cope with the option.

* Type mismatch in prefetch_pages
A variable prefetch_pages is defined as "unsigned" or "int"
in some places. Why don't you define it only once in a header
and include the header in source files?

* Assignment to prefetch_pages
What do "+0.99" means here?   [assign_io_concurrency()]   +             prefetch_pages = new_prefetch_pages+0.99;
You want to do as follows, right?   +             prefetch_pages = (int) ceil(new_prefetch_pages);
