From 065d141af1b4a7c818f643ddc1eab28c9e4de36c Mon Sep 17 00:00:00 2001 From: Steve French Date: Mon, 30 Jul 2018 14:23:58 -0500 Subject: [PATCH] smb3: add tracepoint for session expired or deleted In debugging reconnection problems, want to be able to more easily trace cases in which the server has marked the SMB3 session expired or deleted (to distinguish from timeout cases).
