      Pull bcachefs updates from Kent Overstreet:
      
       - More safety fixes, primarily found by syzbot
      
       - Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
         primarily for testing fsck/recovery in dry run mode, so it shouldn't
         change anything besides disabling writes and holding dirty metadata
         in memory.
      
         The idea here was to reduce the amount of activity if we can't write
         anything out, so that bringing up a filesystem in "super ro" mode
         would be more lilkely to work for data recovery - but norecovery is
         the correct option for this.
      
       - btree_trans->locked; we now track whether a btree_trans has any btree
         nodes locked, and this is used for improved assertions related to
         trans_unlock() and trans_relock(). We'll also be using it for
         improving how we work with lockdep in the future: we don't want
         lockdep to be tracking individual btree node locks because we take
         too many for lockdep to track, and it's not necessary since we have a
         cycle detector.
      
       - Trigger improvements that are prep work for online fsck
      
       - BTREE_TRIGGER_check_repair; this regularizes how we do some repair
         work for extents that goes with running triggers in fsck, and fixes
         some subtle issues with transaction restarts there.
      
       - bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot
         equivalence classes are for when snapshot deletion leaves behind
         redundant snapshot nodes, but snapshot deletion now cleans this up
         right away, so the abstraction doesn't need to leak.
      
       - Improvements to how we resume writing to the journal in recovery. The
         code for picking the new place to write when reading the journal is
         greatly simplified and we also store the position in the superblock
         for when we don't read the journal; this means that we preserve more
         of the journal for list_journal debugging.
      
       - Improvements to sysfs btree_cache and btree_node_cache, for debugging
         memory reclaim.
      
       - We now detect when we've blocked for 10 seconds on the allocator in
         the write path and dump some useful info.
      
       - Safety fixes for devices references: this is a big series that
         changes almost all device lookups to properly check if the device
         exists and take a reference to it.
      
         Previously we assumed that if a bkey exists that references a device
         then the device must exist, and this was enforced in .invalid
         methods, but this was incorrect because it meant device removal
         relied on accounting being correct to not leave keys pointing to
         invalid devices, and that's not something we can assume.
      
         Getting the "pointer to invalid device" checks out of our .invalid()
         methods fixes some long standing device removal bugs; the only
         outstanding bug with device removal now is a race between the discard
         path and deleting alloc info, which should be easily fixed.
      
       - The allocator now prefers not to expand the new
         member_info.btree_allocated bitmap, meaning if repair ever requires
         scanning for btree nodes (because of a corrupt interior nodes) we
         won't have to scan the whole device(s).
      
       - New coding style document, which among other things talks about the
         correct usage of assertions

       "Nine patches this cycle and they split into just three topics:
      
         - Adopt coccinelle's recommendation to adopt str_plural()
      
         - A set of seven patches to refactor kdb_read() to improve both code
           clarity and its discipline with respect to fixed size buffers.
      
           This isn't just a refactor. Between them these also fix a cursor
           movement redraw problem and two buffer overflows (one latent and
           one real, albeit difficult to tickle).
      
         - Fix an NMI-safety problem when enqueuing kdb's keyboard reset code

       "The usual shower of singleton fixes and minor series all over MM,
        documented (hopefully adequately) in the respective changelogs.
        Notable series include:
      
         - Lucas Stach has provided some page-mapping cleanup/consolidation/
           maintainability work in the series "mm/treewide: Remove pXd_huge()

           one test.
      
         - In their series "Memory allocation profiling" Kent Overstreet and
           Suren Baghdasaryan have contributed a means of determining (via
           /proc/allocinfo) whereabouts in the kernel memory is being
           allocated: number of calls and amount of memory.
      
         - Matthew Wilcox has provided the series "Various significant MM
           patches" which does a number of rather unrelated things, but in
           largely similar code sites.
      
         - In his series "mm: page_alloc: freelist migratetype hygiene"
           Johannes Weiner has fixed the page allocator's handling of

         - In the series "make the hugetlb migration strategy consistent"
           Baolin Wang has fixed a hugetlb migration issue, which should

       "This is a light release containing mostly optimizations, code clean-
        ups, and minor bug fixes. This development cycle has focused on non-
        upstream kernel work:
      
         1. Continuing to build upstream CI for NFSD, based on kdevops
      
         2. Backporting NFSD filecache-related fixes to selected LTS kernels
      
        One notable new feature in v6.10 NFSD is the addition of a new netlink
        protocol dedicated to configuring NFSD. A new user space tool,
        nfsdctl, is to be added to nfs-utils. Lots more to come here.
      
        As always I am very grateful to NFSD contributors, reviewers, testers,
        and bug reporters who participated during this cycle"

       "Aside from the usual things this has an arch update for

        This API was intended to generate large 64 byte MemWr TLPs on PCI.
        These days most processors had done this by just repeating writel() in
        a loop. S390 and some new ARM64 designs require a special helper to
        get this to generate.

      Pull clk updates from Stephen Boyd:
       "I'm actually surprised this time. There aren't any new Qualcomm SoC
        clk drivers. And there's zero diff in the core clk framework.
      
        Instead we have new clk drivers for STM and Sophgo, with
        Samsung^WGoogle in third for the diffstat because they introduced HSI0
        and HSI2 clk drivers for Google's GS101 SoC (high speed interface
        things like PCIe, UFS, and MMC).
      
        Beyond those big diffs there's the usual updates to various clk
        drivers for incorrect parent descriptions or mising
        MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
        interesting here.
      
        New Drivers:
         - STM32MP257 SoC clk driver
         - Airoha EN7581 SoC clk driver
         - Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
         - Loongson-2k0500 and Loongson-2k2000 SoC clk driver
         - Add HSI0 and HSI2 clock controllers for Google GS101
         - Add i.MX95 BLK CTL clock driver
      
        Updates:
         - Allocate clk_ops dynamically for SCMI clk driver
         - Add support in qcom RCG and RCG2 for multiple configurations for
           the same frequency
         - Use above support for IPQ8074 NSS port 5 and 6 clocks to resolve
           issues
         - Fix the Qualcomm APSS IPQ5018 PLL to fix boot failures of some
           boards
         - Cleanups and fixes for Qualcomm Stromer PLLs
         - Reduce max CPU frequency on Qualcomm APSS IPQ5018
         - Fix Kconfig dependencies of Qualcomm SM8650 GPU and SC8280XP camera

         - Cleanup downstream remnants related to DisplayPort across Qualcomm

         - Reuse the Huayra APSS register map on Qualcomm MSM8996 CBF PLL
         - Use a specific Qualcomm QCS404 compatible for the otherwise generic

         - Allow choice of manual or firmware-driven control over PLLs, needed

      introduced a bad K&R function definition, which we haven't accepted in a
      long long time.
      
      Gcc seems to let it slide, but clang notices with the appropriate error:

         - Improve timerlat auto-analysis output by replacing '\t' with spaces
           to avoid copy-and-paste issues when reporting problems.
      
         - Make the user-space (-u) option the default, as it is the most
           complete test. Add a -k option to use the in-kernel workload.
      
         - On timerlat top and hist, add a summary with the overall results.
           For instance, the minimum value for all CPUs, the overall average
           and the maximum value from all CPUs.
      
         - timerlat hist was printing initial values (i.e., 0 as max, and ~0
           as min) if the trace stopped before the first Ret-User event. This
           problem was fixed by printing the " - " no value string to the

        For all RTLA tools:
      
         - Add a --warm-up <seconds> option, allowing the workload to run for
           <seconds> before starting to collect results.
      
         - Add a --trace-buffer-size option, allowing the user to set the
           tracing buffer size for -t option. This option is mainly useful for
           reducing the trace file. Now rtla depends on libtracefs >= 1.6.

      Pull tracing user-event updates from Steven Rostedt:
      
       - Minor update to the user_events interface
      
        The ABI of creating a user event states that the fields are separated
        by semicolons, and spaces should be ignored.
      
        But the parsing expected at least one space to be there (which was
        incorrect). Fix the reading of the string to handle fields separated
        by semicolons but no space between them.
      
        This does extend the API sightly as now "field;field" will now be
        parsed and not cause an error. But it should not cause any regressions
        as no logic should expect it to fail.
      
        Note, that the logic that parses the event fields to create the
        trace_event works with no spaces after the semi-colon. It is
        the logic that tests against existing events that is inconsistent.
        This causes registering an event without using spaces to succeed
        if it doesn't exist, but makes the same call that tries to register
        to the same event, but doesn't use spaces, fail.

      Pull tracing ring buffer updates from Steven Rostedt:
       "Add ring_buffer memory mappings.
      
        The tracing ring buffer was created based on being mostly used with
        the splice system call. It is broken up into page ordered sub-buffers
        and the reader swaps a new sub-buffer with an existing sub-buffer
        that's part of the write buffer. It then has total access to the
        swapped out sub-buffer and can do copyless movements of the memory
        into other mediums (file system, network, etc).
      
        The buffer is great for passing around the ring buffer contents in the
        kernel, but is not so good for when the consumer is the user space
        task itself.
      
        A new interface is added that allows user space to memory map the ring
        buffer. It will get all the write sub-buffers as well as reader
        sub-buffer (that is not written to). It can send an ioctl to change
        which sub-buffer is the new reader sub-buffer.
      
        The ring buffer is read only to user space. It only needs to call the
        ioctl when it is finished with a sub-buffer and needs a new sub-buffer
        that the writer will not write over.
      
        A self test program was also created for testing and can be used as an
        example for the interface to user space. The libtracefs (external to
        the kernel) also has code that interacts with this, although it is
        disabled until the interface is in a official release. It can be
        enabled by compiling the library with a special flag. This was used
        for testing applications that perform better with the buffer being
        mapped.
      
        Memory mapped buffers have limitations. The main one is that it can
        not be used with the snapshot logic. If the buffer is mapped,
        snapshots will be disabled. If any logic is set to trigger snapshots
        on a buffer, that buffer will not be allowed to be mapped"

       - Remove sentinel elements from ctl_table structs in kernel/*
      
         Removing sentinels in ctl_table arrays reduces the build time size
         and runtime memory consumed by ~64 bytes per array. Removals for
         net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline
         through their respective subsystems making the next release the most
         likely place where the final series that removes the check for
         proc_name == NULL will land.
      
         This adds to removals already in arch/, drivers/ and fs/.
      
       - Adjust ctl_table definitions and references to allow constification
           - Remove unused ctl_table function arguments
           - Move non-const elements from ctl_table to ctl_table_header
           - Make ctl_table pointers const in ctl_table_root structure
      
         Making the static ctl_table structs const will increase safety by
         keeping the pointers to proc_handler functions in .rodata. Though no
         ctl_tables where made const in this PR, the ground work for making
         that possible has started with these changes sent by Thomas
         Weißschuh.
