From 8a0eebf66e3b1deae036553ba641a9c2bdbae678 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 13 Jan 2011 14:15:50 -0500 Subject: [PATCH] NFS: Fix NFSv3 exclusive open semantics Commit c0204fd2b8fe047b18b67e07e1bf2a03691240cd (NFS: Clean up nfs4_proc_create()) broke NFSv3 exclusive open by removing the code that passes the O_EXCL flag down to nfs3_proc_create(). This patch reverts that offending hunk from the original commit.
