AFAIU, underlying fielesystem need not know about lease time. NFS-Ganesh should send unlock to the backend FS post lease expiry. > > 2> How is the underlying FSAL interpret the owner?? > Can i assume that is will be of certain size so that i can > identify the owner?? > I dont see anyway for FSAL to tell nfsganesha about the lock > owner if there is a conflicting lock. Why does underlying Filesystem > need to know about the lock owner then ?? FWIU, I think current lock owner implementation is not correct. We pass in "state_owner_t " structure contents in binary format to the backend FSAL which shall change with nfs-ganesha reboots. We should be instead sending lock owners sent by NFS-clients along with the size. Underlying filesystem need to know about lock-owners if it needs to distinguish between the lock requests sent by the same NFS-ganesha head, which refer to different NFS clients.
