workqueue: remove unused work_clear_pending()

2014-05-22T15:35:51Z

In 8930caba3dbd ("workqueue: disable irq while manipulating PENDING"), setting last CPU and clearing PENDING got merged into a single operation (set_work_cpu_and_clear_pending()), which resulted that the internal routine work_clear_pending() is not used any more. tj: Minor description tweak.

workqueue: remove unused WORK_CPU_END

2014-05-22T15:35:51Z

WORK_CPU_END is totally unused since 4e8b22bd1a37 ("workqueue: fix pool ID allocation leakage and remove BUILD_BUG_ON() in init_workqueues"). It should be removed. After it is removed, the comment "special cpu IDs" is not precise due to there is only one special CPU ID (WORK_CPU_UNBOUND) left, so we also change this comment to the description for WORK_CPU_UNBOUND. tj: Minor description and comment tweaks.

workqueue: declare system_highpri_wq

2014-05-22T15:35:50Z

system_highpri_wq is exported to modules via EXPORT_SYMBOL_GPL(), but it was forgotten to be declared in workqueue.h. So we add the declaration and a short description for it. tj: Minor comment tweak. Signed-off-by: Lai Jiangshan Signed-off-by: Tejun Heo

workqueue: Remove deprecated system_nrt[_freezable]_wq

system_nrt[_freezable]_wq were deprecated by 3b07e9c ("workqueue: deprecate system_nrt[_freezable]_wq") and have been deprecated for a long time. In addition, these are not used anymore. So, let's remove these functions. Signed-off-by: Jingoo Han Signed-off-by: Tejun Heo

2014-04-01T18:00:07Z

Pull timer changes from Thomas Gleixner: "This assorted collection provides: - A new timer based timer broadcast feature for systems which do not provide a global accessible timer device. That allows those systems to put CPUs into deep idle states where the per cpu timer device stops. - A few NOHZ_FULL related improvements to the timer wheel - The usual updates to timer devices found in ARM SoCs - Small improvements and updates all over the place" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (44 commits) tick: Remove code duplication in tick_handle_periodic() tick: Fix spelling mistake in tick_handle_periodic() x86: hpet: Use proper destructor for delayed work workqueue: Provide destroy_delayed_work_on_stack() clocksource: CMT, MTU2, TMU and STI should depend on GENERIC_CLOCKEVENTS timer: Remove code redundancy while calling get_nohz_timer_target() hrtimer: Rearrange comments in the order struct members are declared timer: Use variable head instead of &work_list in __run_timers() clocksource: exynos_mct: silence a static checker warning arm: zynq: Add support for cpufreq arm: zynq: Don't use arm_global_timer with cpufreq clocksource/cadence_ttc: Overhaul clocksource frequency adjustment clocksource/cadence_ttc: Call clockevents_update_freq() with IRQs enabled clocksource: Add Kconfig entries for CMT, MTU2, TMU and STI sh: Remove Kconfig entries for TMU, CMT and MTU2 ARM: shmobile: Remove CMT, TMU and STI Kconfig entries clocksource: armada-370-xp: Use atomic access for shared registers clocksource: orion: Use atomic access for shared registers clocksource: timer-keystone: Delete unnecessary variable clocksource: timer-keystone: introduce clocksource driver for Keystone ...

workqueue: remove deprecated WQ_NON_REENTRANT

2014-03-29T13:33:03Z

Tejun Heo has made WQ_NON_REENTRANT useless in the dbf2576e37 ("workqueue: make all workqueues non-reentrant"). So remove its usages and definition. This patch doesn't introduce any behavior changes. tj: minor description updates. Signed-off-by: ZhangZhen Sigend-off-by: Tejun Heo Acked-by: James Chapman Acked-by: Ulf Hansson

workqueue: Provide destroy_delayed_work_on_stack()

2014-03-25T16:33:42Z

If a delayed or deferrable work is on stack we need to tell debug objects that we are destroying the timer and the work. Otherwise we leak the tracking object.

workqueue: remove PREPARE_[DELAYED_]WORK()

2014-03-07T15:24:50Z

Peter Hurley noticed that since a2c1c57be8d9 ("workqueue: consider work function when searching for busy work items"), a work item which gets assigned a different work function would break out of the non-reentrancy guarantee as workqueue would consider it a different work item. This is fragile and extremely subtle. PREPARE_[DELAYED_]WORK() have never been used widely and its semantics has always been somewhat iffy. If the work item is known not to be on queue when PREPARE_WORK() is called, there's no difference from using INIT_WORK(). If the work item may be queued at the time of PREPARE_WORK(), we can't really tell whether the old or new function will be executed the next time. We really don't want this level of subtlety in workqueue interface for such marginal use cases. The previous patches converted all existing users away from PREPARE_[DELAYED_]WORK(). Let's remove them. Signed-off-by: Tejun Heo Cc: Peter Hurley Link: http://lkml.kernel.org/g/1392493119-9277-1-git-send-email-peter@hurleysoftware.com
