From 65857d5768f7716da539933c2075d384b117812d Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 24 Sep 2012 13:49:27 -0400 Subject: [PATCH] NFSv4.1: _pnfs_return_layout() shouldn't invalidate the layout on failure Failure of the layoutreturn allocation fails is not a good reason to mark the pnfs_layout_hdr as having failed a layoutget or i/o. Just exit cleanly.
