[PATCH] Add process name to locks warning

From: Andi Kleen
Date: Fri Nov 18 2022 - 19:39:29 EST


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.
