From c82bac6f4b2af18dcb392b10e80c809ee17b2b1b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 6 Nov 2017 15:28:06 -0500 Subject: NFSv4: Don't try to CLOSE if the stateid 'other' field has changed If the stateid is no longer recognised on the server, either due to a restart, or due to a competing CLOSE call, then we do not have to retry. Any open contexts that triggered a reopen of the file, will also act as triggers for any CLOSE for the updated stateids.
