From f2f2494c8aa3cc317572c4674ef256005ebc092b Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 18 Nov 2022 15:43:57 -0800 Subject: [PATCH] Add process name and pid to locks warning It's fairly useless to complain about using an obsolete feature without telling the user which process used it. My Fedora desktop randomly drops this message, but I would really need this patch to figure out what triggers is.
