      mm, kswapd: remove bogus check of balance_classzone_idx · 81c5857b
      Vlastimil Babka authored
      During work on kcompactd integration I have spotted a confusing check of
      balance_classzone_idx, which I believe is bogus.
      
      The balanced_classzone_idx is filled by balance_pgdat() as the highest
      zone it attempted to balance.  This was introduced by commit dc83edd9
      ("mm: kswapd: use the classzone idx that kswapd was using for
      sleeping_prematurely()").
      
      The intention is that (as expressed in today's function names), the
      value used for kswapd_shrink_zone() calls in balance_pgdat() is the same
      as for the decisions in kswapd_try_to_sleep().
      
      An unwanted side-effect of that commit was breaking the checks in
      kswapd() whether there was another kswapd_wakeup with a tighter (=lower)
      classzone_idx.  Commits 215ddd66 ("mm: vmscan: only read
      new_classzone_idx from pgdat when reclaiming successfully") and
      d2ebd0f6
      
       ("kswapd: avoid unnecessary rebalance after an unsuccessful
      balancing") tried to fixed, but apparently introduced a bogus check that
      this patch removes.
      
      Consider zone indexes X < Y < Z, where:
      - Z is the value used for the first kswapd wakeup.
      - Y is returned as balanced_classzone_idx, which means zones with index higher
        than Y (including Z) were found to be unreclaimable.
      - X is the value used for the second kswapd wakeup
      
      The new wakeup with value X means that kswapd is now supposed to balance
      harder all zones with index <= X.  But instead, due to Y < Z, it will go
      sleep and won't read the new value X.  This is subtly wrong.
      
      The effect of this patch is that kswapd will react better in some
      situations, where e.g.  the first wakeup is for ZONE_DMA32, the second is
      for ZONE_DMA, and due to unreclaimable ZONE_NORMAL.  Before this patch,
      kswapd would go sleep instead of reclaiming ZONE_DMA harder.  I expect
      these situations are very rare, and more value is in better
      maintainability due to the removal of confusing and bogus check.

      As CONFIG_DEBUG_PAGEALLOC can be enabled/disabled via kernel parameters
      we can optimize some cases by checking the enablement state.
      
      This is follow-up work for Christian's Optimize CONFIG_DEBUG_PAGEALLOC:
      
        https://lkml.org/lkml/2016/1/27/194
      
      
      
      Remaining work is to make sparc to be aware of this but it looks not
      easy for me so I skip that in this series.

      /proc/kpageflags: return KPF_SLAB for slab tail pages · 0a71649c
      Naoya Horiguchi authored
      
      
      Currently /proc/kpageflags returns just KPF_COMPOUND_TAIL for slab tail
      pages, which is inconvenient when grasping how slab pages are
      distributed (userspace always needs to check which kind of tail pages by
      itself).  This patch sets KPF_SLAB for such pages.
      
      With this patch:
      
        $ grep Slab /proc/meminfo ; tools/vm/page-types -b slab
        Slab:              64880 kB
                     flags      page-count       MB  symbolic-flags                     long-symbolic-flags

      16220 pages equals to 64880 kB, so returned result is consistent with the
      global counter.

      mm: memcontrol: do not bypass slab charge if memcg is offline · fcff7d7e
      Vladimir Davydov authored
      
      
      Slab pages are charged in two steps.  First, an appropriate per memcg
      cache is selected (see memcg_kmem_get_cache) basing on the current
      context, then the new slab page is charged to the memory cgroup which
      the selected cache was created for (see memcg_charge_slab ->
      __memcg_kmem_charge_memcg).  It is OK to bypass kmemcg charge at step 1,
      but if step 1 succeeded and we successfully allocated a new slab page,
      step 2 must be performed, otherwise we would get a per memcg kmem cache
      which contains a slab that does not hold a reference to the memory
      cgroup owning the cache.  Since per memcg kmem caches are destroyed on
      memcg css free, this could result in freeing a cache while there are
      still active objects in it.
      
      However, currently we will bypass slab page charge if the memory cgroup
      owning the cache is offline (see __memcg_kmem_charge_memcg).  This is
      very unlikely to occur in practice, because for this to happen a process
      must be migrated to a different cgroup and the old cgroup must be
      removed while the process is in kmalloc somewhere between steps 1 and 2
      (e.g.  trying to allocate a new page).  Nevertheless, it's still better
      to eliminate such a possibility.

      mm: oom_kill: don't ignore oom score on exiting tasks · 6a618957
      Johannes Weiner authored
      
      
      When the OOM killer scans tasks and encounters a PF_EXITING one, it
      force-selects that task regardless of the score.  The problem is that if
      that task got stuck waiting for some state the allocation site is
      holding, the OOM reaper can not move on to the next best victim.
      
      Frankly, I don't even know why we check for exiting tasks in the OOM
      killer.  We've tried direct reclaim at least 15 times by the time we
      decide the system is OOM, there was plenty of time to exit and free
      memory; and a task might exit voluntarily right after we issue a kill.
      This is testing pure noise.  Remove it.

      copy function, but failed to notice that the header pointer is updated
      between the two copies, resulting in bogus data being copied in the
      latter one.  Fix by keeping the old header pointer.

      there were others archs that needed this, and this one seems to have
      fallen through the cracks.

      Pull libnvdimm updates from Dan Williams:
      
       - Asynchronous address range scrub:
      
           Given the capacities of next generation persistent memory devices a
           scrub operation to find all poison may take 10s of seconds.  We
           want this scrub work to be done asynchronously with the rest of
           system initialization, so we move it out of line from the NFIT
           probing, i.e. acpi_nfit_add().
      
       - Clear poison:
      
           ACPI 6.1 introduces the ability to send "clear error" commands to
           the ACPI0012:00 device representing the root of an "nvdimm bus".
           Similar to relocating a bad block on a disk, this support clears
           media errors in response to a write.
      
       - Persistent memory resource tracking:
      
           A persistent memory range may be designated as simply "reserved" by
           platform firmware in the efi/e820 memory map.  Later when the NFIT
           driver loads it discovers that the range is "Persistent Memory".
      
           The NFIT bus driver inserts a resource to advertise that
           "persistent" attribute in the system resource tree for /proc/iomem
           and kernel-internal usages.
      
       - Miscellaneous cleanups and fixes:
      
           Workaround section misaligned pmem ranges when allocating a struct
           page memmap, fix handling of the read-only case in the ioctl path,
           and clean up block device major number allocation.

      Linus Torvalds authored
      Pull device mapper updates from Mike Snitzer:
      
       - Most attention this cycle went to optimizing blk-mq request-based DM
         (dm-mq) that is used exclussively by DM multipath:
      
           - A stable fix for dm-mq that eliminates excessive context
             switching offers the biggest performance improvement (for both
             IOPs and throughput).
      
           - But more work is needed, during the next cycle, to reduce
             spinlock contention in DM multipath on large NUMA systems.
      
       - A stable fix for a NULL pointer seen when DM stats is enabled on a DM
         multipath device that must requeue an IO due to path failure.
      
       - A stable fix for DM snapshot to disallow the COW and origin devices
         from being identical.  This amounts to graceful failure in the face
         of userspace error because these devices shouldn't ever be identical.
      
       - Stable fixes for DM cache and DM thin provisioning to address crashes
         seen if/when their respective metadata device experiences failures
         that cause the transition to 'fail_io' mode.
      
       - The DM cache 'mq' policy is now an alias for the 'smq' policy.  The
         'smq' policy proved to be consistently better than 'mq'.  As such
         'mq', with all its complex user-facing tunables, has been eliminated.
      
       - Improve DM thin provisioning to consistently return -ENOSPC once the
         thin-pool's data volume is out of space.
      
       - Improve DM core to properly handle error propagation if
         bio_integrity_clone() fails in clone_bio().
      
       - Other small cleanups and improvements to DM core.

      Pull power management and ACPI updates from Rafael Wysocki:
       "This time the majority of changes go into cpufreq and they are
        significant.
      
        First off, the way CPU frequency updates are triggered is different
        now.  Instead of having to set up and manage a deferrable timer for
        each CPU in the system to evaluate and possibly change its frequency
        periodically, cpufreq governors set up callbacks to be invoked by the
        scheduler on a regular basis (basically on utilization updates).  The
        "old" governors, "ondemand" and "conservative", still do all of their
        work in process context (although that is triggered by the scheduler
        now), but intel_pstate does it all in the callback invoked by the
        scheduler with no need for any additional asynchronous processing.
      
        Of course, this eliminates the overhead related to the management of
        all those timers, but also it allows the cpufreq governor code to be
        simplified quite a bit.  On top of that, the common code and data
        structures used by the "ondemand" and "conservative" governors are
        cleaned up and made more straightforward and some long-standing and
        quite annoying problems are addressed.  In particular, the handling of
        governor sysfs attributes is modified and the related locking becomes
        more fine grained which allows some concurrency problems to be avoided
        (particularly deadlocks with the core cpufreq code).
      
        In principle, the new mechanism for triggering frequency updates
        allows utilization information to be passed from the scheduler to
        cpufreq.  Although the current code doesn't make use of it, in the
        works is a new cpufreq governor that will make decisions based on the
        scheduler's utilization data.  That should allow the scheduler and
        cpufreq to work more closely together in the long run.
      
        In addition to the core and governor changes, cpufreq drivers are
        updated too.  Fixes and optimizations go into intel_pstate, the
        cpufreq-dt driver is updated on top of some modification in the
        Operating Performance Points (OPP) framework and there are fixes and
        other updates in the powernv cpufreq driver.
      
        Apart from the cpufreq updates there is some new ACPICA material,
        including a fix for a problem introduced by previous ACPICA updates,
        and some less significant changes in the ACPI code, like CPPC code
        optimizations, ACPI processor driver cleanups and support for loading
        ACPI tables from initrd.
      
        Also updated are the generic power domains framework, the Intel RAPL
        power capping driver and the turbostat utility and we have a bunch of
        traditional assorted fixes and cleanups.
      
        Specifics:
      
         - Redesign of cpufreq governors and the intel_pstate driver to make
           them use callbacks invoked by the scheduler to trigger CPU
           frequency evaluation instead of using per-CPU deferrable timers for
           that purpose (Rafael Wysocki).
      
         - Reorganization and cleanup of cpufreq governor code to make it more
           straightforward and fix some concurrency problems in it (Rafael
           Wysocki, Viresh Kumar).
      
         - Cleanup and improvements of locking in the cpufreq core (Viresh
           Kumar).
      
         - Assorted cleanups in the cpufreq core (Rafael Wysocki, Viresh
           Kumar, Eric Biggers).
      
         - intel_pstate driver updates including fixes, optimizations and a
           modification to make it enable enable hardware-coordinated P-state
           selection (HWP) by default if supported by the processor (Philippe
           Longepe, Srinivas Pandruvada, Rafael Wysocki, Viresh Kumar, Felipe
           Franciosi).
      
         - Operating Performance Points (OPP) framework updates to improve its
           handling of voltage regulators and device clocks and updates of the
           cpufreq-dt driver on top of that (Viresh Kumar, Jon Hunter).
      
         - Updates of the powernv cpufreq driver to fix initialization and
           cleanup problems in it and correct its worker thread handling with
           respect to CPU offline, new powernv_throttle tracepoint (Shilpasri
           Bhat).
      
         - ACPI cpufreq driver optimization and cleanup (Rafael Wysocki).
      
         - ACPICA updates including one fix for a regression introduced by
           previos changes in the ACPICA code (Bob Moore, Lv Zheng, David Box,
           Colin Ian King).
      
         - Support for installing ACPI tables from initrd (Lv Zheng).
      
         - Optimizations of the ACPI CPPC code (Prashanth Prakash, Ashwin
           Chaugule).
      
         - Support for _HID(ACPI0010) devices (ACPI processor containers) and
           ACPI processor driver cleanups (Sudeep Holla).
      
         - Support for ACPI-based enumeration of the AMBA bus (Graeme Gregory,
           Aleksey Makarov).
      
         - Modification of the ACPI PCI IRQ management code to make it treat
           255 in the Interrupt Line register as "not connected" on x86 (as
           per the specification) and avoid attempts to use that value as a
           valid interrupt vector (Chen Fan).
      
         - ACPI APEI fixes related to resource leaks (Josh Hunt).
      
         - Removal of modularity from a few ACPI drivers (BGRT, GHES,
           intel_pmic_crc) that cannot be built as modules in practice (Paul
           Gortmaker).
      
         - PNP framework update to make it treat ACPI_RESOURCE_TYPE_SERIAL_BUS
           as a valid resource type (Harb Abdulhamid).
      
         - New device ID (future AMD I2C controller) in the ACPI driver for
           AMD SoCs (APD) and in the designware I2C driver (Xiangliang Yu).
      
         - Assorted ACPI cleanups (Colin Ian King, Kaiyen Chang, Oleg Drokin).
      
         - cpuidle menu governor optimization to avoid a square root
           computation in it (Rasmus Villemoes).
      
         - Fix for potential use-after-free in the generic device properties
           framework (Heikki Krogerus).
      
         - Updates of the generic power domains (genpd) framework including
           support for multiple power states of a domain, fixes and debugfs
           output improvements (Axel Haslam, Jon Hunter, Laurent Pinchart,
           Geert Uytterhoeven).
      
         - Intel RAPL power capping driver updates to reduce IPI overhead in
           it (Jacob Pan).
      
         - System suspend/hibernation code cleanups (Eric Biggers, Saurabh
           Sengar).
      
         - Year 2038 fix for the process freezer (Abhilash Jindal).
      
         - turbostat utility updates including new features (decoding of more
           registers and CPUID fields, sub-second intervals support, GFX MHz
           and RC6 printout, --out command line option), fixes (syscall jitter
           detection and workaround, reductioin of the number of syscalls
           made, fixes related to Xeon x200 processors, compiler warning
           fixes) and cleanups (Len Brown, Hubert Chrzaniuk, Chen Yu)"

         - separated instruction vs.  data accesses
         - dirty log improvements for huge guests
         - bugfixes and documentation improvements.
      
        x86:
         - Hyper-V VMBus hypercall userspace exit
         - alternative implementation of lowest-priority interrupts using
           vector hashing (for better VT-d posted interrupt support)
         - fixed guest debugging with nested virtualizations
         - improved interrupt tracking in the in-kernel IOAPIC
         - generic infrastructure for tracking writes to guest
           memory - currently its only use is to speedup the legacy shadow
           paging (pre-EPT) case, but in the future it will be used for
           virtual GPUs as well

           fixes handling of explictly specified endianness on big endian
