OpLocks in Samba 1.9.18

[Eloy A. Paris]

Hi,

I have a question regarding the OpLocks that Samba is so proud to have
in 1.9.18 and later: according to an old Speed.txt document, OpLocks
were hard to implement under Unix:

"Samba does not support opportunistic locks because they are very
difficult to do under Unix. Samba can fake them, however, by granting
a oplock whenever a client asks for one."

So, my question is: how did the Samba team do to implement OpLocks?

Thanks,

E.-
