At risk of providing UI, the actual lineage is:

BSD flock() advisory file locks
Unisoft lockf() mandatory record locks
(from Unisoft's 68000 v7 port)
Xenix locking() mandatory record locks
(functionally identical to Unisoft)
System V advisory fcntl() record locks
(adopted by POSIX from SVID)
System V Xenix-compatibility mandatory record locks
(from the SVR3.1/Xenix merge that produced SVR3.2;
deprecated for any use other than allowing old Xenix
programs to run in SVR3.2)

Just in case anyone cares....
