Merge patch series "iomap: buffered io changes"

Browse source

This series contains several fixes and cleanups:

* Renaming bytes_pending/bytes_accounted to
  bytes_submitted/bytes_not_submitted for improved code clarity

* Accounting for unaligned end offsets when truncating read ranges

* Adding documentation for iomap_finish_folio_write() requirements

* Optimizing pending async writeback accounting logic

* Simplifying error handling in ->read_folio_range() for read operations

* Streamlining logic for skipping reads during write operations

* Replacing manual bitmap scanning with find_next_bit() for both dirty
  and uptodate bitmaps, improving performance
