From 304020fe48c6c7fff8b5a38f382b54404f0f79d3 Mon Sep 17 00:00:00 2001 From: Trond Myklebust <trond.myklebust@primarydata.com> Date: Thu, 22 Sep 2016 13:39:18 -0400 Subject: [PATCH] NFSv4: Open state recovery must account for file permission changes If the file permissions change on the server, then we may not be able to recover open state. If so, we need to ensure that we mark the file descriptor appropriately.
