From 27a6c5c50c4bb0c56296f01a3142db796bb01da1 Mon Sep 17 00:00:00 2001 From: Kamalesh Babulal Date: Fri, 6 Oct 2023 17:20:32 +0530 Subject: cgroup: use legacy_name for cgroup v1 disable info cgroup v1 or v2 or both controller names can be passed as arguments to the 'cgroup_no_v1' kernel parameter, though most of the controller's names are the same for both cgroup versions. This can be confusing when both versions are used interchangeably, i.e., passing cgroup_no_v1=io $ sudo dmesg |grep cgroup ... cgroup: Disabling io control group subsystem in v1 mounts cgroup: Disabled controller 'blkio' Make it consistent across the pr_info()'s, by using ss->legacy_name, as the subsystem name, while printing the cgroup v1 controller disabling information in cgroup_init().
