      Pull btrfs updates from David Sterba:
       "Highlights:
      
         - speedup dead root detection during orphan cleanup, eg. when there
           are many deleted subvolumes waiting to be cleaned, the trees are
           now looked up in radix tree instead of a O(N^2) search
      
         - snapshot creation with inherited qgroup will mark the qgroup
           inconsistent, requires a rescan
      
         - send will emit file capabilities after chown, this produces a
           stream that does not need postprocessing to set the capabilities
           again
      
         - direct io ported to iomap infrastructure, cleaned up and simplified
           code, notably removing last use of struct buffer_head in btrfs code
      
        Core changes:
      
         - factor out backreference iteration, to be used by ordinary
           backreferences and relocation code
      
         - improved global block reserve utilization
            * better logic to serialize requests
            * increased maximum available for unlink
            * improved handling on large pages (64K)
      
         - direct io cleanups and fixes
            * simplify layering, where cloned bios were unnecessarily created
              for some cases
            * error handling fixes (submit, endio)
            * remove repair worker thread, used to avoid deadlocks during
              repair
      
         - refactored block group reading code, preparatory work for new type
           of block group storage that should improve mount time on large
           filesystems
      
        Cleanups:
      
         - cleaned up (and slightly sped up) set/get helpers for metadata data
           structure members
      
         - root bit REF_COWS got renamed to SHAREABLE to reflect the that the
           blocks of the tree get shared either among subvolumes or with the
           relocation trees
      
        Fixes:
      
         - when subvolume deletion fails due to ENOSPC, the filesystem is not
           turned read-only
      
         - device scan deals with devices from other filesystems that changed
           ownership due to overwrite (mkfs)
      
         - fix a race between scrub and block group removal/allocation
      
         - fix long standing bug of a runaway balance operation, printing the
           same line to the syslog, caused by a stale status bit on a reloc
           tree that prevented progress
      
         - fix corrupt log due to concurrent fsync of inodes with shared
           extents
      
         - fix space underflow for NODATACOW and buffered writes when it for
           some reason needs to fallback to COW mode"

      Pull DAX updates part two from Darrick Wong:
       "This time around, we're hoisting the DONTCACHE flag from XFS into the
        VFS so that we can make the incore DAX mode changes become effective
        sooner.
      
        We can't change the file data access mode on a live inode because we
        don't have a safe way to change the file ops pointers. The incore
        state change becomes effective at inode loading time, which can happen
        if the inode is evicted. Therefore, we're making it so that
        filesystems can ask the VFS to evict the inode as soon as the last
        holder drops.
      
        The per-fs changes to make this call this will be in subsequent pull
        requests from Ted and myself.
      
        Summary:
      
         - Introduce DONTCACHE flags for dentries and inodes. This hint will
           cause the VFS to drop the associated objects immediately after the
           last put, so that we can change the file access mode (DAX or page
           cache) on the fly"

      Pull DAX updates part one from Darrick Wong:
       "After many years of LKML-wrangling about how to enable programs to
        query and influence the file data access mode (DAX) when a filesystem
        resides on storage devices such as persistent memory, Ira Weiny has
        emerged with a proposed set of standard behaviors that has not been
        shot down by anyone! We're more or less standardizing on the current
        XFS behavior and adapting ext4 to do the same.
      
        This is the first of a handful pull requests that will make ext4 and
        XFS present a consistent interface for user programs that care about
        DAX. We add a statx attribute that programs can check to see if DAX is
        enabled on a particular file. Then, we update the DAX documentation to
        spell out the user-visible behaviors that filesystems will guarantee
        (until the next storage industry shakeup). The on-disk inode flag has
        been in XFS for a few years now.
      
        Summary:
      
         - Clean up io_is_direct.
      
         - Add a new statx flag to indicate when file data access is being
           done via DAX (as opposed to the page cache).
      
         - Update the documentation for how system administrators and
           application programmers can take advantage of the (still
           experimental DAX) feature"

      Pull xfs updates from Darrick Wong:
       "Most of the changes this cycle are refactoring of existing code in
        preparation for things landing in the future.
      
        We also fixed various problems and deficiencies in the quota
        implementation, and (I hope) the last of the stale read vectors by
        forcing write allocations to go through the unwritten state until the
        write completes.
      
        Summary:
      
         - Various cleanups to remove dead code, unnecessary conditionals,
           asserts, etc.
      
         - Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
           redundantly.
      
         - Tighten up our dmesg logging to ensure that everything is prefixed
           with 'XFS' for easier grepping.
      
         - Kill a bunch of typedefs.
      
         - Refactor the deferred ops code to reduce indirect function calls.
      
         - Increase type-safety with the deferred ops code.
      
         - Make the DAX mount options a tri-state.
      
         - Fix some error handling problems in the inode flush code and clean
           up other inode flush warts.
      
         - Refactor log recovery so that each log item recovery functions now
           live with the other log item processing code.
      
         - Fix some SPDX forms.
      
         - Fix quota counter corruption if the fs crashes after running
           quotacheck but before any dquots get logged.
      
         - Don't fail metadata verification on zero-entry attr leaf blocks,
           since they're just part of the disk format now due to a historic
           lack of log atomicity.
      
         - Don't allow SWAPEXT between files with different [ugp]id when
           quotas are enabled.
      
         - Refactor inode fork reading and verification to run directly from
           the inode-from-disk function. This means that we now actually
           guarantee that _iget'ted inodes are totally verified and ready to
           go.
      
         - Move the incore inode fork format and extent counts to the ifork
           structure.
      
         - Scalability improvements by reducing cacheline pingponging in
           struct xfs_mount.
      
         - More scalability improvements by removing m_active_trans from the
           hot path.
      
         - Fix inode counter update sanity checking to run /only/ on debug
           kernels.
      
         - Fix longstanding inconsistency in what error code we return when a
           program hits project quota limits (ENOSPC).
      
         - Fix group quota returning the wrong error code when a program hits
           group quota limits.
      
         - Fix per-type quota limits and grace periods for group and project
           quotas so that they actually work.
      
         - Allow extension of individual grace periods.
      
         - Refactor the non-reclaim inode radix tree walking code to remove a
           bunch of stupid little functions and straighten out the
           inconsistent naming schemes.
      
         - Fix a bug in speculative preallocation where we measured a new
           allocation based on the last extent mapping in the file instead of
           looking farther for the last contiguous space allocation.
      
         - Force delalloc writes to unwritten extents. This closes a stale
           disk contents exposure vector if the system goes down before the
           write completes.

      Pull SELinux updates from Paul Moore:
       "The highlights:
      
         - A number of improvements to various SELinux internal data
           structures to help improve performance. We move the role
           transitions into a hash table. In the content structure we shift
           from hashing the content string (aka SELinux label) to the
           structure itself, when it is valid. This last change not only
           offers a speedup, but it helps us simplify the code some as well.
      
         - Add a new SELinux policy version which allows for a more space
           efficient way of storing the filename transitions in the binary
           policy. Given the default Fedora SELinux policy with the unconfined
           module enabled, this change drops the policy size from ~7.6MB to
           ~3.3MB. The kernel policy load time dropped as well.
      
         - Some fixes to the error handling code in the policy parser to
           properly return error codes when things go wrong"

      mm/migrate.c: attach_page_private already does the get_page · 1966391f
      Hugh Dickins authored
      Just finished bisecting mmotm, to find why a test which used to take
      four minutes now took more than an hour: the __buffer_migrate_page()
      cleanup left behind a get_page() which attach_page_private() now does.
      
      Fixes: cd0f3715 ("mm/migrate.c: call detach_page_private to cleanup code")

      Pull power management updates from Rafael Wysocki:
       "These rework the system-wide PM driver flags, make runtime switching
        of cpuidle governors easier, improve the user space hibernation
        interface code, add intel-speed-select interface documentation, add
        more debug messages to the ACPI code handling suspend to idle, update

        and update two cpuidle drivers, improve the PM-runtime framework,
        update the Intel RAPL power capping driver, update devfreq core and
        drivers, and clean up the cpupower utility.
      
        Specifics:
      
         - Rework the system-wide PM driver flags to make them easier to
           understand and use and update their documentation (Rafael Wysocki,
           Alan Stern).
      
         - Allow cpuidle governors to be switched at run time regardless of
           the kernel configuration and update the related documentation
           accordingly (Hanjun Guo).
      
         - Improve the resume device handling in the user space hibernarion
           interface code (Domenico Andreoli).
      
         - Document the intel-speed-select sysfs interface (Srinivas
           Pandruvada).
      
         - Make the ACPI code handing suspend to idle print more debug
           messages to help diagnose issues with it (Rafael Wysocki).
      
         - Fix a helper routine in the cpufreq core and correct a typo in the
           struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
           Wenhu).
      
         - Update cpufreq drivers:
      
            - Make the intel_pstate driver start in the passive mode by
              default on systems without HWP (Rafael Wysocki).
      
            - Add i.MX7ULP support to the imx-cpufreq-dt driver and add
              i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
      
            - Convert the qoriq cpufreq driver to a platform one, make the
              platform code create a suitable device object for it and add
              platform dependencies to it (Mian Yousaf Kaukab, Geert
              Uytterhoeven).
      
            - Fix wrong compatible binding in the qcom driver (Ansuel Smith).
      
            - Build the omap driver by default for ARCH_OMAP2PLUS (Anders
              Roxell).

              the PSCI driver (Ulf Hansson).
      
         - Fix a reference counting issue related to clock management and
           clean up two oddities in the PM-runtime framework (Rafael Wysocki,
           Andy Shevchenko).
      
         - Add ElkhartLake support to the Intel RAPL power capping driver and
           remove an unused local MSR definition from it (Jacob Pan, Sumeet
           Pawnikar).
      
         - Update devfreq core and drivers:
      
            - Replace strncpy() with strscpy() in the devfreq core and use
              lockdep asserts instead of manual checks for a locked mutex in
              it (Dmitry Osipenko, Krzysztof Kozlowski).
      
            - Add a generic imx bus scaling driver and make it register an
              interconnect device (Leonard Crestez, Gustavo A. R. Silva).
      
            - Make the cpufreq notifier in the tegra30 driver take boosting
              into account and delete an unuseful error message from that
              driver (Dmitry Osipenko, Markus Elfring).

      ubsan: entirely disable alignment checks under UBSAN_TRAP · 9380ce24
      Kees Cook authored
      Commit 8d58f222 ("ubsan: disable UBSAN_ALIGNMENT under
      COMPILE_TEST") tried to fix the pathological results of UBSAN_ALIGNMENT
      with UBSAN_TRAP (which objtool would rightly scream about), but it made
      an assumption about how COMPILE_TEST gets set (it is not set for
      randconfig).  As a result, we need a bigger hammer here: just don't
      allow the alignment checks with the trap mode.

      kasan: fix clang compilation warning due to stack protector · ca734cc6
      Andrey Konovalov authored
      KASAN uses a single cc-option invocation to disable both conserve-stack
      and stack-protector flags.  The former flag is not present in Clang,
      which causes cc-option to fail, and results in stack-protector being
      enabled.
      
      Fix by using separate cc-option calls for each flag.  Also collect all
      flags in a variable to avoid calling cc-option multiple times for
      different files.

      mm: add functions to track page directory modifications · d8626138
      Joerg Roedel authored
      Patch series "mm: Get rid of vmalloc_sync_(un)mappings()", v3.
      
      After the recent issue with vmalloc and tracing code[1] on x86 and a
      long history of previous issues related to the vmalloc_sync_mappings()
      interface, I thought the time has come to remove it.  Please see [2],
      [3], and [4] for some other issues in the past.
      
      The patches add tracking of page-table directory changes to the vmalloc
      and ioremap code.  Depending on which page-table levels changes have
      been made, a new per-arch function is called:
      arch_sync_kernel_mappings().
      
      On x86-64 with 4-level paging, this function will not be called more
      than 64 times in a systems runtime (because vmalloc-space takes 64 PGD
      entries which are only populated, but never cleared).
      
      As a side effect this also allows to get rid of vmalloc faults on x86,
      making it safe to touch vmalloc'ed memory in the page-fault handler.
      Note that this potentially includes per-cpu memory.
      
      This patch (of 7):
      
      Add page-table allocation functions which will keep track of changed
      directory entries.  They are needed for new PGD, P4D, PUD, and PMD
      entries and will be used in vmalloc and ioremap code to decide whether
      any changes in the kernel mappings need to be synchronized between
      page-tables in the system.

      mm: remove vmalloc_user_node_flags · 041de93f
      Christoph Hellwig authored
      Open code it in __bpf_map_area_alloc, which is the only caller.  Also
      clean up __bpf_map_area_alloc to have a single vmalloc call with slightly
      different flags instead of the current two different calls.
      
      For this to compile for the nommu case add a __vmalloc_node_range stub to
      nommu.c.
