Subject: [PATCH 1/2] cifs: change tcon status when need_reconnect is set on it
Date: Tue, 6 Feb 2024 15:00:46 +0000 [thread overview]
Message-ID: <20240206150047.29046-1-sprasad@microsoft.com> (raw)
From: Shyam Prasad N <sprasad@microsoft.com>
When a tcon is marked for need_reconnect, the intention
is to have it reconnected.
This change adjusts tcon->status in cifs_tree_connect
when need_reconnect is set. Also, this change has a minor
correction in resetting need_reconnect on success. It makes
sure that it is done with tc_lock held.
