From: Yu Liao <liaoyu15@huawei.com> mainline inclusion from mainline-v6.12-rc1 commit 7ebd84d627e40cb9fb12b338588e81b6cca371e3 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IDC9YK Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... -------------------------------- When build with CONFIG_GROUP_SCHED_WEIGHT && !CONFIG_FAIR_GROUP_SCHED, the idle member is not defined: kernel/sched/ext.c:3701:16: error: 'struct task_group' has no member named 'idle' 3701 | if (!tg->idle) | ^~ Fix this by putting 'idle' under new CONFIG_GROUP_SCHED_WEIGHT. tj: Move idle field upward to avoid breaking up CONFIG_FAIR_GROUP_SCHED block.
