Subject: [PATCH 2/5] cifs: change tcon status when need_reconnect is set on it
Date: Thu,  1 Feb 2024 11:15:27 +0000	[thread overview]
Message-ID: <20240201111530.17194-2-sprasad@microsoft.com> (raw)
In-Reply-To: <20240201111530.17194-1-sprasad@microsoft.com>

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.
