From 1ed3a8539af7b36aa5c977f304e80f7fc8d27bfc Mon Sep 17 00:00:00 2001 From: Benny Halevy Date: Wed, 15 Jun 2011 11:39:57 -0400 Subject: [PATCH] NFSv4.1: need to put_layout_hdr on _pnfs_return_layout error path We always get a reference on the layout header and we rely on nfs4_layoutreturn_release to put it. If we hit an allocation error before starting the rpc proc we bail out early without dereferncing the layout header properly.
