Thanks for having a look. That blurb in the changelog refers to the[...]
kerneldoc comment over write_one_page below...
No existing caller uses this on normal files, so
none of them need it.

/**
- * write_one_page - write out a single page and optionally wait on I/O
+ * write_one_page - write out a single page and wait on I/O
* @page: the page to write
- * @wait: if true, wait on writeout
*
* The page must be locked by the caller and will be unlocked upon return.
*
- * write_one_page() returns a negative error code if I/O failed.
+ * write_one_page() returns a negative error code if I/O failed. Note that
+ * the address_space is not marked for error. The caller must do this if
+ * needed.
...specifically the single sentence in the comment above.
As I said, none of the existing callers need to set an error in the
mapping when this fails, so I just added this to make it clear for any
new callers in the future.
