From 7380020e77b61361207420e78a9da925bc79ab4b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 6 Nov 2017 15:28:07 -0500 Subject: pNFS: Retry NFS4ERR_OLD_STATEID errors in layoutreturn-on-close If our layoutreturn on close operation returns an NFS4ERR_OLD_STATEID, then try to update the stateid and retry. We know that there should be no further LAYOUTGET requests being launched.
