Merge tag 'sched_urgent_for_v6.17_rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler fixes from Borislav Petkov:
- Fix a stall on the CPU offline path due to mis-counting a deadline
server task twice as part of the runqueue's running tasks count
- Fix a realtime tasks starvation case where failure to enqueue a timer
whose expiration time is already in the past would cause repeated
attempts to re-enqueue a deadline server task which leads to starving
the former, realtime one
- Prevent a delayed deadline server task stop from breaking the
per-runqueue bandwidth tracking
- Have a function checking whether the deadline server task has
stopped, return the correct value
* tag 'sched_urgent_for_v6.17_rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
sched/deadline: Don't count nr_running for dl_server proxy tasks
sched/deadline: Fix RT task potential starvation when expiry time passed
sched/deadline: Always stop dl-server before changing parameters
sched/deadline: Fix dl_server_stopped()
