From 335b7b62ffb69d18055f2bb6f3a029263a07c735 Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Wed, 16 Jan 2019 11:12:41 -0800 Subject: CIFS: Respect reconnect in MTU credits calculations Every time after a session reconnect we don't need to account for credits obtained in previous sessions. Introduce new struct cifs_credits which contains both credits value and reconnect instance of the time those credits were taken. Modify a routine that add credits back to handle the reconnect instance by assuming zero credits if the reconnect happened after the credits were obtained and before we decided to add them back due to some errors during sending. This patch fixes the MTU credits cases. The subsequent patch will handle non-MTU ones.
