From 5bc2afc2b53fc73f154e6344cd898585628e6d27 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 23 Sep 2013 18:01:28 -0400 Subject: NFSv4: Honour the 'opened' parameter in the atomic_open() filesystem method Determine if we've created a new file by examining the directory change attribute and/or the O_EXCL flag. This fixes a regression when doing a non-exclusive create of a new file. If the FILE_CREATED flag is not set, the atomic_open() command will perform full file access permissions checks instead of just checking for MAY_OPEN.
