If a flock is emulated on the server side with mandatory locks (which
is what we only have for SMB2 without POSIX extensions) then we should
maintain the same logic on the client. Otherwise you get different
behavior depending on the caching policies currently in effect on the
client side. You may consider testing with both modes when
leases/oplocks are on and off.

Hm.. you're right, the write will fail on the server side without
cache.

I guess we should document current cifs behaviour in the flock man page.
