[OmniOS-discuss] flock from RHEL7 client to OmniOS

[Derek Yarnell]

Is anyone else seeing a problem with flock over NFS on more recent
clients including RHEL7 (I am guessing recent fedora releases too)?
fcntl works fine but flock has an error.  Our Nexenta 3.x and NetApp
servers work fine it seems but we also see the same issue with our Dell
FluidFS (though we are at least a full revision behind on it).  I have
tested r151008 and r151010 both exhibit the same behavior for OmniOS.
