That's a really open ended question.
Ceph in general implements cluster-wide POSIX file locks, internally
managing the locks based on the same clustering & distribution
mechanisms as it uses for coordinating its own work. From the view
pointer of a filesystem user, it should "just work", though naturally
with network operations latency is higher than with purely local
locks.
The cfuse client does not support them, currently. This is merely a
case of "oh nobody wrote that code yet".
What are you interested in knowing?
