Subject: [PATCH v1 01/13] cifs: call wake_up(&server->response_q) inside of cifs_reconnect()
Date: Mon, 24 Feb 2020 14:14:58 +0100	[thread overview]
Message-ID: <20200224131510.20608-2-metze@samba.org> (raw)
In-Reply-To: <20200224131510.20608-1-metze@samba.org>

This means it's consistently called and the callers don't need to
care about it.
