Because by default, get_maintainer looks for a matching
file entry in MAINTAINERS.  Failing that, it looks at
one year of git history.  In this case, no work has been
done on the file for quite awhile.

--git-blame can be added to the get_maintainer.pl command
line to look for % of authorship by line and commit count.

Adding --git-blame can take a long time to run, that's why
it's not on by default.  Also, very old history can give
invalid email addresses as people move around and email
addresses decay.

If you always want to find original authors, you could
use a .get_maintainer.conf file with --git-blame in it.

$ time ./scripts/get_maintainer.pl --git-blame -f drivers/staging/octeon/ethernet-tx.c
