This passes our kafs tests where a few of the issues fixed here had been seen. I made the framework use 9p and no related issues were seen there either.

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.
