A descendent of the original code is still present in DragonFlyBSD:
The facility still exists in NetBSD but it has been reimplemented on top
of puffs, the Pass-to-Userspace Framework File System development
It survived in FreeBSD for a long time, but eventually was removed in 2012
rather than being made multiprocessor-safe.
It also got removed from OpenBSD in 2011.

Trafalgar: Northerly or northeasterly 4 or 5, increasing 6 or 7 later, perhaps
gale 8 in northeast. Moderate or rough, but slight or moderate in southeast.
