From 95b72eb0bdef6476b7e73061f0382adf46c5495a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 20 Apr 2012 19:24:51 -0400 Subject: NFSv4: Ensure we do not reuse open owner names The NFSv4 spec is ambiguous about whether or not it is permissible to reuse open owner names, so play it safe. This patch adds a timestamp to the state_owner structure, and combines that with the IDA based uniquifier. Fixes a regression whereby the Linux server returns NFS4ERR_BAD_SEQID.
