Subject: [PATCH v3 02/22] smb/server: fix possible refcount leak in smb2_sess_setup()
Date: Tue, 14 Oct 2025 15:18:57 +0800 [thread overview]
Message-ID: <20251014071917.3004573-3-chenxiaosong.chenxiaosong@linux.dev> (raw)
In-Reply-To: <20251014071917.3004573-1-chenxiaosong.chenxiaosong@linux.dev>
From: ZhangGuoDong <zhangguodong@kylinos.cn>
Reference count of ksmbd_session will leak when session need reconnect.
Fix this by adding the missing ksmbd_user_session_put().
