Hi Tejun,
After merging the cgroup tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:
kernel/cgroup/cgroup.c: In function 'init_cgroup_root':
kernel/cgroup/cgroup.c:1867:3: warning: ignoring return value of 'strscpy', declared with attribute warn_unused_result [-Wunused-result]
strscpy(root->release_agent_path, opts->release_agent, PATH_MAX);
^
kernel/cgroup/cgroup.c:1869:3: warning: ignoring return value of 'strscpy', declared with attribute warn_unused_result [-Wunused-result]
strscpy(root->name, opts->name, MAX_CGROUP_ROOT_NAMELEN);

strscpy(buf, cft->name, CGROUP_FILE_NAME_MAX);
