Well, we all "maintain" it, meaning that we keep it compilable. However,
I'm sure that no one checks the functionality. There are no regression
tests, and seems to be no users. I recently found that if you run
GENERIC and 'kldload svr4.ko', the socket layer compatibility will
be broken, since SVR4 requires COMPAT_OLDSOCK. And that has been for
decades, and no one notices that. I bet there are simply no users.
Towing this piece of code into the future is just a waste of time.
Totus tuus, Glebius.
