Subject: [PATCHSET sched_ext/for-6.19-fixes] sched_ext: Fix missing post-enqueue handling in move_local_task_to_local_dsq()
Date: Thu, 11 Dec 2025 12:48:07 -1000 [thread overview]
Message-ID: <20251211224809.3383633-1-tj@kernel.org> (raw)
Hello,
move_local_task_to_local_dsq() was missing post-enqueue handling which
matters now that scx_bpf_dsq_move() can be called while the CPU is busy.
