Adding an #ifdef __FreeBSD__ to a FreeBSD-specific header may seem odd, but these headers are used on non-FreeBSD systems during the bootstrap tools phase. Originally submitted downstream as https://reviews.freebsd.org/D26193 Reviewed-by: Ryan Moeller <ryan@iXsystems.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> Closes #10863
