- Make the two messages differ and print the error code.

You answered that a WARN before every late failure tells the two
apart. The header write failure has no WARN, and the late paths use
WARN_ON_ONCE. So from the second failure on, both cases print the same
single line, and the error of the header write is not printed at all.
