Concurrent access of the object via Rados API...

[Dennis Chen <kernel.org.gnu@xxxxxxxxx>]

Hello,

For the case of multiple clients(separate process) accessing an object
in the cluster, is the exclusive protection of the shared object
needed for the caller?

Process A::rados::ioctx.write(obj, ...)
Process B::rados::ioctx.write(obj, ...)

or:

Process A::
    mylock.lock();
    ioctx.write(obj, ..)
    mylock.unlock()

Process B::
    mylock.lock();
    ioctx.write(obj, ..)
    mylock.unlock()

which one is correct?
