Tejun Heo 57ec081869 sched_ext, sched/core: Don't call scx_group_set_weight() prematurely from sched_create_group() ... commit 33796b9187 upstream. During task_group creation, sched_create_group() calls scx_group_set_weight() with CGROUP_WEIGHT_DFL to initialize the sched_ext portion. This is premature and ends up calling ops.cgroup_set_weight() with an incorrect @cgrp before ops.cgroup_init() is called. sched_create_group() should just initialize SCX related fields in the new task_group. Fix it by factoring out scx_tg_init() from sched_init() and making sched_create_group() call that function instead of scx_group_set_weight(). v2: Retain CONFIG_EXT_GROUP_SCHED ifdef in sched_init() as removing it leads to build failures on !CONFIG_GROUP_SCHED configs.
