From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Paul Koetsier Date: Thu, 27 Oct 2022 19:29:28 +0200 Subject: [PATCH] libmultipath: fix 'show paths format' failure Prevent 'multipathd show paths format "%c"' from failing on orphan paths. For orphan paths the checker class isn't set, which caused snprint_path_checker() to fail which in turn caused 'show paths format' to fail when the format string contained "%c".
