From 33fa5c8b8a7dbe6353a56eaa654b790348890d42 Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Thu, 3 Jan 2019 16:45:13 -0800 Subject: [PATCH] CIFS: Do not set credits to 1 if the server didn't grant anything Currently we reset the number of total credits granted by the server to 1 if the server didn't grant us anything int the response. This violates the SMB3 protocol - we need to trust the server and use the credit values from the response. Fix this by removing the corresponding code.
