Subject: [PATCH AUTOSEL 5.17 19/20] cifs: when a channel is not found for server, log its connection id
Date: Tue, 21 Jun 2022 16:50:09 -0400	[thread overview]
Message-ID: <20220621205010.250185-19-sashal@kernel.org> (raw)
In-Reply-To: <20220621205010.250185-1-sashal@kernel.org>

From: Shyam Prasad N <sprasad@microsoft.com>

[ Upstream commit 5d24968f5b7e00bae564b1646c3b9e0e3750aabe ]

cifs_ses_get_chan_index gets the index for a given server pointer.
When a match is not found, we warn about a possible bug.
However, printing details about the non-matching server could be
more useful to debug here.
