The intention of the patches is to do the latter. Apart from the patch
that rounds up file_ra_state->ra_pages, I don't poke file_ra_state
anywhere and it is updated only at the end after we enforce
minimum-block-size constraint (page_cache_ra_order).

Could you elaborate more on where I do both? Maybe I am missing
something and I could change it in the next series.

The previous series was trying to do both but I intentially stuck to
updating the ra_state at the end in this series.
