From 98f4eb25c4e23e202ace7e5bf64acc6458b4caff Mon Sep 17 00:00:00 2001 From: Shyam Prasad N Date: Tue, 14 Jun 2022 11:47:24 +0000 Subject: [PATCH] cifs: when a channel is not found for server, log its connection id 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.
