From b365b9d404b7376c60c91cd079218bfef11b7822 Mon Sep 17 00:00:00 2001 From: Steve French Date: Sun, 6 Apr 2025 14:09:19 -0500 Subject: smb311 client: fix missing tcon check when mounting with linux/posix extensions When mounting the same share twice, once with the "linux" mount parameter (or equivalently "posix") and then once without (or e.g. with "nolinux"), we were incorrectly reusing the same tree connection for both mounts. This meant that the first mount of the share on the client, would cause subsequent mounts of that same share on the same client to ignore that mount parm ("linux" vs. "nolinux") and incorrectly reuse the same tcon.
