From d03d9fe476ea81ad3be25967ef35a671dbd79b55 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 21 Jul 2016 21:55:42 -0400 Subject: [PATCH] nfsd: remove unnecessary positive-dentry check vfs_{create,mkdir,mknod} each begin with a call to may_create(), which returns EEXIST if the object already exists. This check is therefore unnecessary. (In the NFSv2 case, nfsd_proc_create also has such a check. Contrary to RFC 1094, our code seems to believe that a CREATE of an existing file should succeed. I'm leaving that behavior alone.) Signed-off-by: J.
