Subject[PATCH 4.4 070/190] pNFS/flexfiles: missing error code in ff_layout_alloc_lseg()
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@oracle.com>


[ Upstream commit 662f9a105b4322b8559d448f86110e6ec24b8738 ]

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.
