From: Greg Kroah-Hartman
Date: Thu Oct 06 2016 - 04:58:27 EST


4.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

commit 73e6c5d854d3f7f75e8b46d3e54aeb5d83fe6b1f upstream.

According to the errata
https://www.rfc-editor.org/errata_search.php?rfc=5661&eid=2751
we should always send layout commit after a commit to DS.

Fixes: bc7d4b8fd091 ("nfs/filelayout: set layoutcommit...")
