From e179e80c5d4fef458c3cbc3ad4ea17c6d42c0446 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 4 Sep 2024 10:24:59 -1000 Subject: sched: Introduce CONFIG_GROUP_SCHED_WEIGHT sched_ext will soon add cgroup cpu.weigh support. The cgroup interface code is currently gated behind CONFIG_FAIR_GROUP_SCHED. As the fair class and/or SCX may implement the feature, put the interface code behind the new CONFIG_CGROUP_SCHED_WEIGHT which is selected by CONFIG_FAIR_GROUP_SCHED. This allows either sched class to enable the itnerface code without ading more complex CONFIG tests. When !CONFIG_FAIR_GROUP_SCHED, a dummy version of sched_group_set_shares() is added to support later CONFIG_CGROUP_SCHED_WEIGHT && !CONFIG_FAIR_GROUP_SCHED builds. No functional changes.
