sched_ext: Merge branch 'for-7.2-fixes' into for-7.3
Pull to receive:
c10b216a072f ("sched/core: Handle pick_task() releasing the rq lock")
f3629c63a4af ("sched/core: Make core-sched flips wait for in-flight selections")
ffaab58d2175 ("sched_ext: Replace SCX_RQ_BAL_KEEP with a dispatch verdict return")
3dd52416e44a ("sched_ext: Fix this_rq() assumptions in dispatch kfuncs")
f2da9587118d ("sched_ext: Count rq lock releases in rq->scx.lock_drop_seq")
d954004205c1 ("sched_ext: Fix rq->core_pick corruption under core scheduling")
for the pending core scheduling follow-ups and to resolve the conflicts
with the code reorganization and cap gate work on for-7.3.
ffaab58d2175 converts scx_dispatch_sched() to a dispatch verdict return
which for-7.3 moved from ext.c into inlines.h. Resolved by applying the
conversion to the relocated copy and combining balance_one()'s verdict
returns with the scx_task_can_stay_on_cpu() gate from the cap work.
ffaab58d2175 and 3dd52416e44a update scx_bpf_sub_dispatch() which
for-7.3 moved into sub.c. Resolved by applying the scx_locked_rq()
switch and the verdict test to the sub.c copy.
f2da9587118d instruments the open-coded lock releases in
consume_remote_task() which for-7.3 folded into switch_rq_lock().
Resolved by keeping the accounting in switch_rq_lock() which covers all
its callers.
d954004205c1 widens the put_prev_task_scx() WARN suppression to all
core-sched rqs on the same condition that for-7.3 gated with
scx_task_can_stay_on_cpu(). Resolved by combining both.
