I see this regularly in the Jenkins results:
https://jenkins.freebsd.org/job/FreeBSD_HEAD-tests/1108/console

sys/fifo/fifo_misc:main  ->  WARNING pid 60945 (fifo_misc): ioctl sign-extension ioctl ffffffff8004667e

WARNING pid 60945 (fifo_misc): ioctl sign-extension ioctl ffffffff8004667d

Need to figure out where what the root cause is for this warning.

Closing bug because the issue was relatively benign, so fixing on stable/9 isn't needed.
