From 9a7fe9e8900baad5f6643000ea48b91aee895165 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 12 Feb 2014 08:17:00 -0500 Subject: NFSv4.1: Minor optimisation in get_layout_by_fh_locked() If the filehandles match, but the igrab() fails, or the layout is freed before we can get it, then just return NULL.
