From 809fd143de8805970eec02c27c0bc2622a6ecbda Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 23 Oct 2014 19:33:14 +0300 Subject: [PATCH] NFSv4: Ensure nfs_atomic_open set the dentry verifier on ENOENT If the OPEN rpc call to the server fails with an ENOENT call, nfs_atomic_open will create a negative dentry for that file, however it currently fails to call nfs_set_verifier(), thus causing the dentry to be immediately revalidated on the next call to nfs_lookup_revalidate() instead of following the usual lookup caching rules.
