From 94f873717571c759b7928399cbbddfa3d569bd01 Mon Sep 17 00:00:00 2001 From: Aurelien Aptel Date: Thu, 22 Sep 2016 07:38:50 +0200 Subject: fs/cifs: keep guid when assigning fid to fileinfo When we open a durable handle we give a Globally Unique Identifier (GUID) to the server which we must keep for later reference e.g. when reopening persistent handles on reconnection. Without this the GUID generated for a new persistent handle was lost and 16 zero bytes were used instead on re-opening.
