Dear RT Folks, This is the RT stable review cycle of patch 3.4.106-rt132-rc3. 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 3/20/2015. Enjoy, -- Steve To build 3.4.106-rt132-rc3 directly, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.4.tar.xz http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.4.106.xz http://www.kernel.org/pub/linux/kernel/projects/rt/3.4/patch-3.4.106-rt132-rc3.patch.xz You can also build from 3.4.106-rt131 by applying the incremental patch: http://www.kernel.org/pub/linux/kernel/projects/rt/3.4/incr/patch-3.4.106-rt131-rt132-rc3.patch.xz Changes from 3.4.106-rt131: --- Daniel Wagner (1): work-simple: Simple work queue implemenation Josh Cartwright (1): lockdep: selftest: fix warnings due to missing PREEMPT_RT conditionals Mike Galbraith (4): x86: UV: raw_spinlock conversion scheduling while atomic in cgroup code sunrpc: make svc_xprt_do_enqueue() use get_cpu_light() fs,btrfs: fix rt deadlock on extent_buffer->lock Paul Gortmaker (1): sas-ata/isci: dont't disable interrupts in qc_issue handler Sebastian Andrzej Siewior (3): gpio: omap: use raw locks for locking rt-mutex: avoid a NULL pointer dereference on deadlock arm/futex: disable preemption during futex_atomic_cmpxchg_inatomic() Steven Rostedt (1): create-rt-enqueue Steven Rostedt (Red Hat) (1): Linux 3.4.106-rt132-rc3 Thomas Gleixner (14): rtmutex: Simplify rtmutex_slowtrylock() rtmutex: Simplify and document try_to_take_rtmutex() rtmutex: No need to keep task ref for lock owner check rtmutex: Clarify the boost/deboost part rtmutex: Document pi chain walk rtmutex: Simplify remove_waiter() rtmutex: Confine deadlock logic to futex rtmutex: Cleanup deadlock detector debug logic rtmutex: Avoid pointless requeueing in the deadlock detection chain walk futex: Make unlock_pi more robust futex: Use futex_top_waiter() in lookup_pi_state() futex: Split out the waiter check from lookup_pi_state() futex: Split out the first waiter attachment from lookup_pi_state() futex: Simplify futex_lock_pi_atomic() and make it more robust Yadi.hu (1): ARM: enable irq in translation/section permission fault handlers Yong Zhang (1): ARM: cmpxchg: define __HAVE_ARCH_CMPXCHG for armv6 and later ---- arch/arm/include/asm/cmpxchg.h | 2 + arch/arm/include/asm/futex.h | 4 + arch/arm/mm/fault.c | 6 + arch/x86/include/asm/uv/uv_bau.h | 12 +- arch/x86/include/asm/uv/uv_hub.h | 2 +- arch/x86/kernel/apic/x2apic_uv_x.c | 12 +- arch/x86/platform/uv/tlb_uv.c | 30 +- arch/x86/platform/uv/uv_time.c | 21 +- drivers/gpio/gpio-omap.c | 76 ++--- drivers/scsi/libsas/sas_ata.c | 4 +- fs/btrfs/ctree.c | 4 +- include/linux/rtmutex.h | 8 +- include/linux/work-simple.h | 24 ++ kernel/futex.c | 407 +++++++++++-------------- kernel/rt.c | 8 +- kernel/rtmutex-debug.c | 5 +- kernel/rtmutex-debug.h | 7 +- kernel/rtmutex-tester.c | 4 +- kernel/rtmutex.c | 603 +++++++++++++++++++++++++++---------- kernel/rtmutex.h | 7 +- kernel/rtmutex_common.h | 22 +- kernel/sched/Makefile | 1 + kernel/sched/work-simple.c | 172 +++++++++++ lib/locking-selftest.c | 27 ++ localversion-rt | 2 +- mm/memcontrol.c | 13 +- net/sunrpc/svc_xprt.c | 4 +- 27 files changed, 1002 insertions(+), 485 deletions(-) Diff from -rc2: --- diff --git a/localversion-rt b/localversion-rt index 8f02c3a9ffa7..c70c2e0b2d32 100644 --- a/localversion-rt +++ b/localversion-rt @@ -1 +1 @@ --rt132-rc2 +-rt132-rc3 diff --git a/mm/memcontrol.c b/mm/memcontrol.c index 8c3dd645ac10..8cfff961ad4b 100644 --- a/mm/memcontrol.c +++ b/mm/memcontrol.c @@ -2016,13 +2016,15 @@ static bool consume_stock(struct mem_cgroup *memcg) { struct memcg_stock_pcp *stock; bool ret = true; + int cpu; - stock = &get_cpu_var(memcg_stock); + cpu = get_cpu_light(); + stock = &per_cpu(memcg_stock, cpu); if (memcg == stock->cached && stock->nr_pages) stock->nr_pages--; else /* need to call res_counter_charge */ ret = false; - put_cpu_var(memcg_stock); + put_cpu_light(); return ret; } -- 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
