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.

...specifically the single sentence in the comment above.
As I said, none of the existing callers need to set an error in the

Well, everything looks great, then.
thanks,
