From 58c3c55f3888fd2482545dfc902b9cb38458e404 Mon Sep 17 00:00:00 2001 From: Dmitry Yakunin Date: Thu, 8 Oct 2020 20:59:27 +0300 Subject: [PATCH] lib: ignore invalid mounts in cg_init_map In case of bad entries in /proc/mounts just skip cgroup cache initialization. Cgroups in output will be shown as "unreachable:cgroup_id".
