Hi Christian, Jeff, Gao,
Here are some additional patches for my netfs-lib tree:
(1) Mark netfs_unbuffered_write_iter_locked() static as it's only used in
the file in which it is defined.
(2) Display a counter for DIO writes in /proc/fs/netfs/stats.
(3) Fix the interaction between write-streaming (dirty data in
non-uptodate pages) and the culling of a cache file trying to write
that to the cache.
(4) Fix the loop that unmarks folios after writing to the cache. The
xarray iterator only advances the index by 1, so if we unmarked a
multipage folio and that got split before we advance to the next
folio, we see a repeat of a fragment of the folio.
(5) Fix a mixup with signed/unsigned offsets when prepping for writing to
the cache that leads to missing error detection.
(6) Fix a wrong ifdef hiding a wait.
David
