But same for read locks, when you
query them with F_OFD_GETLK.
It doesn't sound ambiguous to me,
you get the valid owner, and you can
iterate them if you kill them in a
process (same as for read locks).

Just a way to abruptly kill offending lockers,
as that most likely means the process hanged
(I have a 3rd party code that drives the locking,
so it can't be trusted not to hang).
Its not essential though, for sure.
Curiosity also plays the role here. :)
Though if you don't want, I can as well
not add a TODO comment to the code.
