We already track the page uptodate status based on the buffer uptodate
status, which is updated whenever reading or zeroing blocks.
This code has been there since commit a ptool commit in 2002, which
claims to:
"merge" the 2.4 fsx fix for block size < page size to 2.5. This needed
major changes to actually fit.
and isn't present in other writepage implementations.
