From 662f9a105b4322b8559d448f86110e6ec24b8738 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 20 May 2017 00:31:12 +0300 Subject: [PATCH] pNFS/flexfiles: missing error code in ff_layout_alloc_lseg() If xdr_inline_decode() fails then we end up returning ERR_PTR(0). The caller treats NULL returns as -ENOMEM so it doesn't really hurt runtime, but obviously we intended to set an error code here.
