update_watchdog_all_cpus() now passes errors from watchdog_park_threads() up to functions in the call chain. This allows watchdog_enable_all_cpus() and proc_watchdog_update() to handle such errors too. Signed-off-by:

Move watchdog_disable_all_cpus() outside of the ifdef so that it is available if CONFIG_SYSCTL is not defined. This is preparation for "watchdog: implement error handling in update_watchdog_all_cpus() and callers". Signed-off-by:

Ulrich Obergfell authored
The original watchdog_park_threads() function that was introduced by commit 81a4beef ("watchdog: introduce watchdog_park_threads() and watchdog_unpark_threads()") takes a very simple approach to handle errors returned by kthread_park(): It attempts to roll back all watchdog threads to the unparked state. However, this may be undesired behaviour from the perspective of the caller which may want to handle errors as appropriate in its specific context. Currently, there are two possible call chains: - watchdog suspend/resume interface lockup_detector_suspend watchdog_park_threads - write to parameters in /proc/sys/kernel proc_watchdog_update watchdog_enable_all_cpus update_watchdog_all_cpus watchdog_park_threads Instead of 'blindly' attempting to unpark the watchdog threads if a kthread_park() call fails, the new approach is to disable the lockup detectors in the above call chains. Failure becomes visible to the user as follows: - error messages from lockup_detector_suspend() or watchdog_enable_all_cpus() - the state that can be read from /proc/sys/kernel/watchdog_enabled - the 'write' system call in the latter call chain returns an error I did not experience kthread_park() failures in practice, I used some instrumentation to fake error returns from kthread_park() in order to test the patches. This patch (of 5): Restore the previous value of watchdog_thresh _and_ sample_period if proc_watchdog_update() returns an error. The variables must be consistent to avoid false positives of the lockup detectors. Signed-off-by:

Make struct callback_head aligned to size of pointer. On most architectures it happens naturally due ABI requirements, but some architectures (like CRIS) have weird ABI and we need to ask it explicitly. The alignment is required to guarantee that bits 0 and 1 of @next will be clear under normal conditions -- as long as we use call_rcu(), call_rcu_bh(), call_rcu_sched(), or call_srcu() to queue callback. This guarantee is important for few reasons: - future call_rcu_lazy() will make use of lower bits in the pointer; - the structure shares storage spacer in struct page with @compound_head, which encode PageTail() in bit 0. The guarantee is needed to avoid false-positive PageTail(). False postive PageTail() caused crash on crisv32[1]. It happend due misaligned task_struct->rcu, which was byte-aligned.

A node can mount multiple ocfs2 volumes. And if thread names are same for each volume/domain, it will bring inconvenience when analyzing problems because we have to identify which volume/domain the messages belong to. Since thread name will be printed to messages, so add volume uuid or dlm name to thread name can benefit problem analysis. Signed-off-by:

Currently cluster allocation is always trying to find a victim chain (a chian has most space), and this may lead to poor performance because of discontiguous allocation in some scenarios. Our test case is block size 4k, cluster size 1M and mount option with localalloc=2048 (2G), since a gd is 32256M (about 31.5G) and a localalloc window is only 2G, creating 50G file will result in 2G from gd0, 2G from gd1, ... One way to improve performance is enlarge localalloc window size (max 31104M), but this will make end user feel that about 30G is suddenly "missing", and localalloc currently do not support steal, which means one node cannot use another node's localalloc even it is not used in fact. So using the last gd to record the allocation and continues with the gd if it has enough space for a localalloc window can make the allocation as more contiguous as possible. Our test result is below (evaluated in IOPS), which is using iometer running in VM, dynamic vhd virtual disk stored in ocfs2.

The comment here says that it is checking for invalid bits. But, the mask is *actually* checking to ensure that _any_ valid bit is set, which is quite different. Without this check, an unexpected bit could get set on an inotify object. Since these bits are also interpreted by the fsnotify/dnotify code, there is the potential for an object to be mishandled inside the kernel. For instance, can we be sure that setting the dnotify flag FS_DN_RENAME on an inotify watch is harmless? Add the actual check which was intended. Retain the existing inotify bits are being added to the watch. Plus, this is existing behavior which would be nice to preserve. I did a quick sniff test that inotify functions and that my 'inotify-tools' package passes 'make check'. Signed-off-by:

There was a report that my patch: inotify: actually check for invalid bits in sys_inotify_add_watch() broke CRIU. The reason is that CRIU looks up raw flags in /proc/$pid/fdinfo/* to figure out how to rebuild inotify watches and then passes those flags directly back in to the inotify API. One of those flags (FS_EVENT_ON_CHILD) is set in mark->mask, but is not part of the inotify API. It is used inside the kernel to _implement_ inotify but it is not and has never been part of the API. My patch above ensured that we only allow bits which are part of the API (IN_ALL_EVENTS). This broke CRIU. FS_EVENT_ON_CHILD is really internal to the kernel. It is set _anyway_ on all inotify marks. So, CRIU was really just trying to set a bit that was already set. This patch hides that bit from fdinfo. CRIU will not see the bit, not try to set it, and should work as before. We should not have been exposing this bit in the first place, so this is a good patch independent of the CRIU problem. Signed-off-by:Andrey Wagin <avagin@gmail.com> Acked-by:

Pull power management and ACPI updates from Rafael Wysocki: "Quite a new features are included this time. First off, the Collaborative Processor Performance Control interface (version 2) defined by ACPI will now be supported on ARM64 along with a cpufreq frontend for CPU performance scaling. Second, ACPI gets a new infrastructure for the early probing of IRQ chips and clock sources (along the lines of the existing similar mechanism for DT). Next, the ACPI core and the generic device properties API will now support a recently introduced hierarchical properties extension of the _DSD (Device Specific Data) ACPI device configuration object. If the ACPI platform firmware uses that extension to organize device properties in a hierarchical way, the kernel will automatically handle it and make those properties available to device drivers via the generic device properties API. It also will be possible to build the ACPICA's AML interpreter debugger into the kernel now and use that to diagnose AML-related problems more efficiently. In the future, this should make it possible to single-step AML execution and do similar things. Interesting stuff, although somewhat experimental at this point. Finally, the PM core gets a new mechanism that can be used by device drivers to distinguish between suspend-to-RAM (based on platform firmware support) and suspend-to-idle (or other variants of system suspend the platform firmware is not involved in) and possibly optimize their device suspend/resume handling accordingly. In addition to that, some existing features are re-organized quite substantially. First, the ACPI-based handling of PCI host bridges on x86 and ia64 is unified and the common code goes into the ACPI core (so as to reduce code duplication and eliminate non-essential differences between the two architectures in that area). Second, the Operating Performance Points (OPP) framework is reorganized to make the code easier to find and follow. Next, the cpufreq core's sysfs interface is reorganized to get rid of the "primary CPU" concept for configurations in which the same performance scaling settings are shared between multiple CPUs. Finally, some interfaces that aren't necessary any more are dropped from the generic power domains framework. On top of the above we have some minor extensions, cleanups and bug fixes in multiple places, as usual. Specifics: - ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng). The most significant change is to allow the AML debugger to be built into the kernel. On top of that there is an update related to the NFIT table (the ACPI persistent memory interface) and a few fixes and cleanups. - ACPI CPPC2 (Collaborative Processor Performance Control v2) support along with a cpufreq frontend (Ashwin Chaugule). This can only be enabled on ARM64 at this point. - New ACPI infrastructure for the early probing of IRQ chips and clock sources (Marc Zyngier). - Support for a new hierarchical properties extension of the ACPI _DSD (Device Specific Data) device configuration object allowing the kernel to handle hierarchical properties (provided by the platform firmware this way) automatically and make them available to device drivers via the generic device properties interface (Rafael Wysocki). - Generic device properties API extension to obtain an index of certain string value in an array of strings, along the lines of of_property_match_string(), but working for all of the supported firmware node types, and support for the "dma-names" device property based on it (Mika Westerberg). - ACPI core fix to parse the MADT (Multiple APIC Description Table) entries in the order expected by platform firmware (and mandated by the specification) to avoid confusion on systems with more than 255 logical CPUs (Lukasz Anaczkowski). - Consolidation of the ACPI-based handling of PCI host bridges on x86 and ia64 (Jiang Liu). - ACPI core fixes to ensure that the correct IRQ number is used to represent the SCI (System Control Interrupt) in the cases when it has been re-mapped (Chen Yu). - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede). - ACPI EC driver fixes (Lv Zheng). - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri Kosina, Rami Rosen, Rasmus Villemoes). - New mechanism in the PM core allowing drivers to check if the platform firmware is going to be involved in the upcoming system suspend or if it has been involved in the suspend the system is resuming from at the moment (Rafael Wysocki). This should allow drivers to optimize their suspend/resume handling in some cases and the changes include a couple of users of it (the i8042 input driver, PCI PM). - PCI PM fix to prevent runtime-suspended devices with PME enabled from being resumed during system suspend even if they aren't configured to wake up the system from sleep (Rafael Wysocki). - New mechanism to report the number of a wakeup IRQ that woke up the system from sleep last time (Alexandra Yates). - Removal of unused interfaces from the generic power domains framework and fixes related to latency measurements in that code (Ulf Hansson, Daniel Lezcano). - cpufreq core sysfs interface rework to make it handle CPUs that share performance scaling settings (represented by a common cpufreq policy object) more symmetrically (Viresh Kumar). This should help to simplify the CPU offline/online handling among other things. - cpufreq core fixes and cleanups (Viresh Kumar). - intel_pstate fixes related to the Turbo Activation Ratio (TAR) mechanism on client platforms which causes the turbo P-states range to vary depending on platform firmware settings (Srinivas Pandruvada). - intel_pstate sysfs interface fix (Prarit Bhargava). - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G Bhat, Luis de Bethencourt). - cpuidle mvebu driver cleanups (Russell King). - OPP (Operating Performance Points) framework code reorganization to make it more maintainable (Viresh Kumar). - Intel Broxton support for the RAPL (Running Average Power Limits) power capping driver (Amy Wiles). - Assorted power management code fixes and cleanups (Dan Carpenter, Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus Villemoes)" * tag 'pm+acpi-4.4-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (108 commits) cpufreq: postfix policy directory with the first CPU in related_cpus cpufreq: create cpu/cpufreq/policyX directories cpufreq: remove cpufreq_sysfs_{create|remove}_file() cpufreq: create cpu/cpufreq at boot time cpufreq: Use cpumask_copy instead of cpumask_or to copy a mask cpufreq: ondemand: Drop unnecessary locks from update_sampling_rate() PM / Domains: Merge measurements for PM QoS device latencies PM / Domains: Don't measure ->start|stop() latency in system PM callbacks PM / clk: Fix broken build due to non-matching code and header #ifdefs ACPI / Documentation: add copy_dsdt to ACPI format options ACPI / sysfs: correctly check failing memory allocation ACPI / video: Add a quirk to force native backlight on Lenovo IdeaPad S405 ACPI / CPPC: Fix potential memory leak ACPI / CPPC: signedness bug in register_pcc_channel() ACPI / PAD: power_saving_thread() is not freezable ACPI / PM: Fix incorrect wakeup IRQ setting during suspend-to-idle ACPI: Using correct irq when waiting for events ACPI: Use correct IRQ when uninstalling ACPI interrupt handler cpuidle: mvebu: disable the bind/unbind attributes and use builtin_platform_driver cpuidle: mvebu: clean up multiple platform drivers ... -

Pull s390 updates from Martin Schwidefsky: "There is only one new feature in this pull for the 4.4 merge window, most of it is small enhancements, cleanup and bug fixes: - Add the s390 backend for the software dirty bit tracking. This adds two new pgtable functions pte_clear_soft_dirty and pmd_clear_soft_dirty which is why there is a hit to arch/x86/include/asm/pgtable.h in this pull request. - A series of cleanup patches for the AP bus, this includes the removal of the support for two outdated crypto cards (PCICC and PCICA). - The irq handling / signaling on buffer full in the runtime instrumentation code is dropped. - Some micro optimizations: remove unnecessary memory barriers for a couple of functions: [smb_]rmb, [smb_]wmb, atomics, bitops, and for spin_unlock. Use the builtin bswap if available and make test_and_set_bit_lock more cache friendly. - Statistics and a tracepoint for the diagnose calls to the hypervisor. - The CPU measurement facility support to sample KVM guests is improved. - The vector instructions are now always enabled for user space processes if the hardware has the vector facility. This simplifies the FPU handling code. The fpu-internal.h header is split into fpu internals, api and types just like x86. - Cleanup and improvements for the common I/O layer. - Rework udelay to solve a problem with kprobe. udelay has busy loop semantics but still uses an idle processor state for the wait" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (66 commits) s390: remove runtime instrumentation interrupts s390/cio: de-duplicate subchannel validation s390/css: unneeded initialization in for_each_subchannel s390/Kconfig: use builtin bswap s390/dasd: fix disconnected device with valid path mask s390/dasd: fix invalid PAV assignment after suspend/resume s390/dasd: fix double free in dasd_eckd_read_conf s390/kernel: fix ptrace peek/poke for floating point registers s390/cio: move ccw_device_stlck functions s390/cio: move ccw_device_call_handler s390/topology: reduce per_cpu() invocations s390/nmi: reduce size of percpu variable s390/nmi: fix terminology s390/nmi: remove casts s390/nmi: remove pointless error strings s390: don't store registers on disabled wait anymore s390: get rid of __set_psw_mask() s390/fpu: split fpu-internal.h into fpu internals, api, and type headers s390/dasd: fix list_del corruption after lcu changes s390/spinlock: remove unneeded serializations at unlock ... -
