Merge tag 'wq-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue updates from Tejun Heo: - Concurrency-managed per-cpu work items that hog CPUs and delay the execution of other work items are now automatically detected and excluded from concurrency management. Reporting on such work items can also be enabled through a config option. - Added tools/workqueue/wq_monitor.py which improves visibility into workqueue usages and behaviors. - Arnd's minimal fix for gcc-13 enum warning on 32bit compiles, superseded by commit afa4bb778e48 in mainline. * tag 'wq-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: Disable per-cpu CPU hog detection when wq_cpu_intensive_thresh_us is 0 workqueue: Fix WARN_ON_ONCE() triggers in worker_enter_idle() workqueue: fix enum type for gcc-13 workqueue: Track and monitor per-workqueue CPU time usage workqueue: Report work funcs that trigger automatic CPU_INTENSIVE mechanism workqueue: Automatically mark CPU-hogging work items CPU_INTENSIVE workqueue: Improve locking rule description for worker fields workqueue: Move worker_set/clr_flags() upwards workqueue: Re-order struct worker fields workqueue: Add pwq->stats[] and a monitoring script Further upgrade queue_work_on() comment
