So I had to convert it as well, hence a few more change splitups. Changes: * Check also raised lists from irq_work_needs_cpu() (thanks Peterz) * Comment on SMP functions priority in generic_smp_call_function_single_interrupt() because IPI callbacks there are often synchronous as opposed to irq works. (thanks Peterz) * s/native_send_call_func_single_ipi/native_send_call_func_single_ipi (thanks Eric Dumazet) * Only build irq_work_queue_on() on CONFIG_SMP, fixes some broken builds * Convert full nohz timer list kick git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git timers/nohz-irq-work-v6 Thanks, Frederic --- Frederic Weisbecker (6): irq_work: Split raised and lazy lists irq_work: Implement remote queueing nohz: Support nohz full remote kick nohz: Switch to nohz full remote kick on timer enqueue nohz: Use nohz own full kick on 2nd task enqueue nohz: Use IPI implicit full barrier against rq->nr_running r/w include/linux/irq_work.h | 5 ++++ include/linux/tick.h | 9 +++++- kernel/irq_work.c | 76 ++++++++++++++++++++++++++++++------------------ kernel/sched/core.c | 22 ++++++++------ kernel/sched/sched.h | 12 ++++++-- kernel/smp.c | 9 ++++++ kernel/time/tick-sched.c | 10 ++++--- 7 files changed, 97 insertions(+), 46 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
