Dear RT Folks, This is the RT stable review cycle of patch 3.18.27-rt27-rc1. Please scream at me if I messed something up. Please test the patches too. The -rc release will be uploaded to kernel.org and will be deleted when the final release is out. This is just a review release (or release candidate). The pre-releases will not be pushed to the git repository, only the final release is. If all goes well, this patch will be converted to the next main release on 3/7/2016. Enjoy, -- Steve To build 3.18.27-rt27-rc1 directly, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.18.tar.xz http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.18.27.xz http://www.kernel.org/pub/linux/kernel/projects/rt/3.18/patch-3.18.27-rt27-rc1.patch.xz You can also build from 3.18.27-rt26 by applying the incremental patch: http://www.kernel.org/pub/linux/kernel/projects/rt/3.18/incr/patch-3.18.27-rt26-rt27-rc1.patch.xz Changes from 3.18.27-rt26: --- Clark Williams (1): rcu/torture: Comment out rcu_bh ops on PREEMPT_RT_FULL Mike Galbraith (3): sched,rt: __always_inline preemptible_lazy() drm,radeon,i915: Use preempt_disable/enable_rt() where recommended drm,i915: Use local_lock/unlock_irq() in intel_pipe_update_start/end() Sebastian Andrzej Siewior (11): sched: reset task's lockless wake-queues on fork() ptrace: don't open IRQs in ptrace_freeze_traced() too early net: move xmit_recursion to per-task variable on -RT preempt-lazy: Add the lazy-preemption check to preempt_schedule() softirq: split timer softirqs out of ksoftirqd net: provide a way to delegate processing a softirq to ksoftirqd latencyhist: disable jump-labels kernel: migrate_disable() do fastpath in atomic & irqs-off kernel: softirq: unlock with irqs on kernel/stop_machine: partly revert "stop_machine: Use raw spinlocks" kernel: sched: Fix preempt_disable_ip recodring for preempt_disable() Steven Rostedt (Red Hat) (1): Linux 3.18.27-rt27-rc1 Thomas Gleixner (1): tick/broadcast: Make broadcast hrtimer irqsafe Yang Shi (3): arm64: replace read_lock to rcu lock in call_step_hook trace: Use rcuidle version for preemptoff_hist trace point f2fs: Mutex can't be used by down_write_nest_lock() ---- arch/Kconfig | 1 + arch/arm64/kernel/debug-monitors.c | 21 +++--- drivers/gpu/drm/i915/i915_irq.c | 2 + drivers/gpu/drm/i915/intel_sprite.c | 11 ++-- drivers/gpu/drm/radeon/radeon_display.c | 2 + fs/f2fs/f2fs.h | 4 +- include/linux/ftrace.h | 12 ++++ include/linux/interrupt.h | 8 +++ include/linux/netdevice.h | 9 +++ include/linux/sched.h | 3 +- include/trace/events/hist.h | 1 + kernel/fork.c | 1 + kernel/ptrace.c | 6 +- kernel/rcu/rcutorture.c | 7 ++ kernel/sched/core.c | 52 ++++++++------- kernel/softirq.c | 112 ++++++++++++++++++++++++++++---- kernel/stop_machine.c | 40 +++--------- kernel/time/tick-broadcast-hrtimer.c | 1 + kernel/trace/trace_irqsoff.c | 8 +-- localversion-rt | 2 +- net/core/dev.c | 43 ++++++++++-- 21 files changed, 249 insertions(+), 97 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
