[PATCH v1 0/2] Tiny optimization for large read operations

[Chi Zhiling]

From: Chi Zhiling <chizhiling@xxxxxxxxxx>

This series contains two patches,

1. Skip calling is_partially_uptodate for entire folio to save time,
I have reviewed the mpage and iomap implementations and didn't spot any
issues, but this change likely needs more thorough review.

2. Skip calling filemap_uptodate if there are ready folios in the batch,
This might save a few milliseconds in practice, but I didn't observe
measurable improvements in my tests.

Changes from rfc:
- update commits
- switch to the new solution which provided by Matthew Wilcox.
