From b79a4a1b45b2543e38026303a1956bdc0aababa0 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 23 Dec 2008 15:21:41 -0500 Subject: NFSv4: Fix state recovery when the client runs over the grace period If the client for some reason is not able to recover all its state within the time allotted for the grace period, and the server reboots again, the client is not allowed to recover the state that was 'lost' using reboot recovery.
