Date: Mon, 7 Nov 2016 14:04:46 +0100 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Trond Myklebust <trond.myklebust@...marydata.com>, Anna Schumaker <Anna.Schumaker@...app.com>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 39/72] NFSv4: Open state recovery must account for file permission changes From: Trond Myklebust <trond.myklebust@...marydata.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 304020fe48c6c7fff8b5a38f382b54404f0f79d3 upstream. 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.
