Subject: [PATCH 1/3] cifs: log session id when a matching ses is not found
Date: Thu, 22 Jun 2023 18:16:02 +0000	[thread overview]
Message-ID: <20230622181604.4788-1-sprasad@microsoft.com> (raw)

We do not log the session id in crypt_setup when a matching
session is not found. Printing the session id helps debugging
here. This change does just that.
