A lot of activities this\n round including considerable API and behavior cleanups.\n\n * delayed_work combines a timer and a work item. The handling of the\n timer part has always been a bit clunky leading to confusing\n cancelation API with weird corner-case behaviors. delayed_work is\n updated to use new IRQ safe timer and cancelation now works as\n expected.\n\n * Another deficiency of delayed_work was lack of the counterpart of\n mod_timer() which led to cancel+queue combinations or open-coded\n timer+work usages. mod_delayed_work[_on]() are added.\n\n These two delayed_work changes make delayed_work provide interface\n and behave like timer which is executed with process context.\n\n * A work item could be executed concurrently on multiple CPUs, which\n is rather unintuitive and made flush_work() behavior confusing and\n half-broken under certain circumstances. This problem doesn\u0027t\n exist for non-reentrant workqueues. While non-reentrancy check\n isn\u0027t free, the overhead is incurred only when a work item bounces\n across different CPUs and even in simulated pathological scenario\n the overhead isn\u0027t too high.\n\n All workqueues are made non-reentrant. This removes the\n distinction between flush_[delayed_]work() and\n flush_[delayed_]_work_sync(). The former is now as strong as the\n latter and the specified work item is guaranteed to have finished\n execution of any previous queueing on return.\n\n * In addition to the various bug fixes, Lai redid and simplified CPU\n hotplug handling significantly.\n\n * Joonsoo introduced system_highpri_wq and used it during CPU\n hotplug.\n\n There are two merge commits - one to pull in IRQ safe timer from\n tip/timers/core and the other to pull in CPU hotplug fixes from\n wq/for-3.6-fixes as Lai\u0027s hotplug restructuring depended on them.\"\n\nFixed a number of trivial conflicts, but the more interesting conflicts\nwere silent ones where the deprecated interfaces had been used by new\ncode in the merge window, and thus didn\u0027t cause any real data conflicts.\n\nTejun pointed out a few of them, I fixed a couple more.\n\n* \u0027for-3.7\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits)\n workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending()\n workqueue: use cwq_set_max_active() helper for workqueue_set_max_active()\n workqueue: introduce cwq_set_max_active() helper for thaw_workqueues()\n workqueue: remove @delayed from cwq_dec_nr_in_flight()\n workqueue: fix possible stall on try_to_grab_pending() of a delayed work item\n workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback()\n workqueue: use __cpuinit instead of __devinit for cpu callbacks\n workqueue: rename manager_mutex to assoc_mutex\n workqueue: WORKER_REBIND is no longer necessary for idle rebinding\n workqueue: WORKER_REBIND is no longer necessary for busy rebinding\n workqueue: reimplement idle worker rebinding\n workqueue: deprecate __cancel_delayed_work()\n workqueue: reimplement cancel_delayed_work() using try_to_grab_pending()\n workqueue: use mod_delayed_work() instead of __cancel + queue\n workqueue: use irqsafe timer for delayed_work\n workqueue: clean up delayed_work initializers and add missing one\n workqueue: make deferrable delayed_work initializer names consistent\n workqueue: cosmetic whitespace updates for macro definitions\n workqueue: deprecate system_nrt[_freezable]_wq\n workqueue: deprecate flush[_delayed]_work_sync()\n ...\n" }, { "commit": "7a84428af7ca6a847f058c9ff244a18a2664fd1b", "tree": "e6c573c701736a75d618b670d66e98398b62769f", "parents": [ "1e08ec4a130e2745d96df169e67c58df98a07311" ], "author": { "name": "Alex Williamson", "email": "alex.williamson@redhat.com", "time": "Fri Sep 21 11:58:03 2012 -0600" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Sun Sep 23 13:50:15 2012 +0200" }, "message": "KVM: Add resampling irqfds for level triggered interrupts\n\nTo emulate level triggered interrupts, add a resample option to\nKVM_IRQFD.
