This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 809fd143de8805970eec02c27c0bc2622a6ecbda upstream.
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.
