#     Merge tag 'sched_ext-for-6.12-rc1-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
#     
#     Pull sched_ext fixes from Tejun Heo:
#     
#      - When sched_ext is in bypass mode (e.g. while disabling the BPF
#        scheduler), it was using one DSQ to implement global FIFO scheduling
#        as all it has to do is guaranteeing reasonable forward progress.
#     
#        On multi-socket machines, this can lead to live-lock conditions under
#        certain workloads. Fixed by splitting the queue used for FIFO
#        scheduling per NUMA node. This required several preparation patches.
#     
#      - Hotplug tests on powerpc could reliably trigger deadlock while
#        enabling a BPF scheduler.
#     
#        This was caused by cpu_hotplug_lock nesting inside scx_fork_rwsem and
#        then CPU hotplug path trying to fork a new thread while holding
#        cpu_hotplug_lock.
#     
#        Fixed by restructuring locking in enable and disable paths so that
#        the two locks are not coupled. This required several preparation
#        patches which also fixed a couple other issues in the enable path.
#     
#      - A build fix for !CONFIG_SMP
#     
#      - Userspace tooling sync and updates
#
