From 209379924a85029394adce5ad0cfc7692091303c Mon Sep 17 00:00:00 2001 From: Shyam Prasad N Date: Mon, 30 Oct 2023 11:00:10 +0000 Subject: [PATCH] cifs: do not reset chan_max if multichannel is not supported at mount commit 6e5e64c9477d58e73cb1a0e83eacad1f8df247cf upstream. If the mount command has specified multichannel as a mount option, but multichannel is found to be unsupported by the server at the time of mount, we set chan_max to 1. Which means that the user needs to remount the share if the server starts supporting multichannel. This change removes this reset. What it means is that if the user specified multichannel or max_channels during mount, and at this time, multichannel is not supported, but the server starts supporting it at a later point, the client will be capable of scaling out the number of channels.
