From 369d6b7f00977eb9090212d4a47ac71f3ec5c217 Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Mon, 2 Mar 2015 16:46:09 -0500 Subject: NFS: Fix stateid used for NFS v4 closes After 566fcec60 the client uses the "current stateid" from the nfs4_state structure to close a file. This could potentially contain a delegation stateid, which is disallowed by the protocol and causes servers to return NFS4ERR_BAD_STATEID. This patch restores the (correct) behavior of sending the open stateid to close a file.
