Hello, Trond! Could you point to idea how userspace process can know about lost lock on NFSv4 server (due to server reboot) ? See "case -NFS4ERR_DENIED" at nfs4_reclaim_locks(): http://lxr.free-electrons.com/source/fs/nfs/nfs4state.c#L1184 --- Thanks, Vitaliy -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
