In current git, they look pretty symmetric to me, and it boots and runs.

Applied, thanks.

Looks like Adrian just hit that too.  As Linus pointed out,
__generic_file_aio_write_nolock calls generic_write_checks at line
2383, and that's available at line 1831, which the error message
helpfully points out.  I don't see how gcc can be claiming that the
function body isn't available when it's telling you exactly where it
is.
