      Pull driver core updates from Greg KH:
       "Here is the large set of driver core changes for 6.3-rc1.
      
        There's a lot of changes this development cycle, most of the work
        falls into two different categories:
      
         - fw_devlink fixes and updates. This has gone through numerous review
           cycles and lots of review and testing by lots of different devices.
           Hopefully all should be good now, and Saravana will be keeping a
           watch for any potential regression on odd embedded systems.
      
         - driver core changes to work to make struct bus_type able to be
           moved into read-only memory (i.e. const) The recent work with Rust
           has pointed out a number of areas in the driver core where we are
           passing around and working with structures that really do not have
           to be dynamic at all, and they should be able to be read-only
           making things safer overall. This is the contuation of that work
           (started last release with kobject changes) in moving struct
           bus_type to be constant. We didn't quite make it for this release,
           but the remaining patches will be finished up for the release after
           this one, but the groundwork has been laid for this effort.
      
        Other than that we have in here:
      
         - debugfs memory leak fixes in some subsystems
      
         - error path cleanups and fixes for some never-able-to-be-hit
           codepaths.
      
         - cacheinfo rework and fixes
      
         - Other tiny fixes, full details are in the shortlog
      
        All of these have been in linux-next for a while with no reported
        problems"
      
      [ Geert Uytterhoeven points out that that last sentence isn't true, and
        that there's a pending report that has a fix that is queued up - Linus ]

       "Here is the "boring" staging driver update for 6.3-rc1.
      
        Nothing major in here at all, it's just lots of tiny code cleanups to
        bring some of the staging drivers more in line with the real portion
        of the kernel (apis and coding style.) Overall we remove more lines of
        code than we add, always a nice result.
      
        The big work was done by Martin Kaiser and Philipp Hortmann, both
        tackling some of the older wifi drivers, removing unused code and
        structures and a file in one case.

      cifs: Fix cifs_writepages_region() · ab7362d0
      David Howells authored
      Fix the cifs_writepages_region() to just jump over members of the batch
      that have been cleaned up rather than counting them as skipped.
      
      Unlike the other "skip_write" cases, this situation happens even for
      WB_SYNC_ALL, simply because the page has either been cleaned by somebody
      else, or was truncated.
      
      So in this case we're not "skipping" the write, we simply no longer need
      any write at all, so it's very different from the other skip_write cases.
      
      And we definitely shouldn't stop writing the rest just because of too
      many of these cases (or because we want to be rescheduled).

       "Nothing exciting at all for modules for v6.3.
      
        The biggest change is just the change of INSTALL_MOD_DIR from "extra"
        to "updates" which I found lingered for ages for no good reason while
        testing the CXL mock driver [0].
      
        The CXL mock driver has no kconfig integration and requires building
        an external module... and re-building the *rest* of the production
        drivers. This mock driver when loaded but not the production ones will
        crash.
      
        All this can obviously be fixed by integrating kconfig semantics into
        such test module, however that's not desirable by the maintainer, and
        so sensible defaults must be used to ensure a default "make
        modules_install" will suffice for most distros which do not have a
        file like /etc/depmod.d/dist.conf with something like `search updates
        extra built-in`.
      
        Since most distros rely on kmod and since its inception the "updates"
        directory is always in the search path it makes more sense to use that
        than the "extra" which only *some* RH based systems rely on.
      
        All this stuff has been on linux-next for a while"

      Pull perf tools updates from Arnaldo Carvalho de Melo:
       "Miscellaneous:
      
         - Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
      
         - Add support for retire latency feature (pipeline stall of a
           instruction compared to the previous one, in cycles) present on
           some Intel processors.
      
         - Add 'perf c2c' report option to show false sharing with adjacent
           cachelines, to be used in machines with cacheline prefetching,
           where accesses to a cacheline brings the next one too.
      
         - Skip 'perf test bpf' when the required kernel-debuginfo package
           isn't installed.
      
         - Avoid d3-flame-graph package dependency in 'perf script flamegraph',
           making this feature more generally available.
      
         - Add JSON metric events to present CPI stall cycles in Power10.
      
         - Assorted improvements/refactorings on the JSON metrics parsing
           code.
      
        perf lock contention:
      
         - Add -o/--lock-owner option:
      
              $ sudo ./perf lock contention -abo -- ./perf bench sched pipe

           Please note that to have the -b option (BPF) working above one has
           to build with BUILD_BPF_SKEL=1.
      
         - Add more 'perf test' entries to test these new features.
      
        perf script:
      
         - Add 'cgroup' field for 'perf script' output:
      
              $ perf record --all-cgroups -- true
              $ perf script -F comm,pid,cgroup
                        true 337112  /user.slice/user-657345.slice/user@657345.service/...

         - Add support for showing branch speculation information in 'perf
           script' and in the 'perf report' raw dump (-D).
      
        perf record:
      
         - Fix 'perf record' segfault with --overwrite and --max-size.
      
        perf test/bench:
      
         - Switch basic BPF filtering test to use syscall tracepoint to avoid
           the variable number of probes inserted when using the previous
           probe point (do_epoll_wait) that happens on different CPU
           architectures.
      
         - Fix DWARF unwind test by adding non-inline to expected function in
           a backtrace.
      
         - Use 'grep -c' where the longer form 'grep | wc -l' was being used.
      
         - Add getpid and execve benchmarks to 'perf bench syscall'.
      
        Intel PT:
      
         - Add support for synthesizing "cycle" events from Intel PT traces as
           we support "instruction" events when Intel PT CYC packets are
           available. This enables much more accurate profiles than when using
           the regular 'perf record -e cycles' (the default) when the workload
           lasts for very short periods (<10ms).
      
         - .plt symbol handling improvements, better handling IBT (in the past
           MPX) done in the context of decoding Intel PT processor traces,
           IFUNC symbols on x86_64, static executables, understanding .plt.got
           symbols on x86_64.
      
         - Add a 'perf test' to test symbol resolution, part of the .plt
           improvements series, this tests things like symbol size in contexts
           where only the symbol start is available (kallsyms), etc.
      
         - Better handle auxtrace/Intel PT data when using pipe mode (perf
           record sleep 1|perf report).
      
         - Fix symbol lookup with kcore with multiple segments match stext,
           getting the symbol resolution to just show DSOs as unknown.
      
        ARM:
      
         - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
           Macrocell v4).
      
         - Ensure ARM64 CoreSight timestamps don't go backwards.
      
         - Document that ARM64 SPE (Statistical Profiling Extension) is used
           with 'perf c2c/mem'.
      
         - Add raw decoding for ARM64 SPEv1.2 previous branch address.
      
         - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1,
           TLB, cache, branch, PE utilization and instruction mix metrics.
      
         - Update decoder code for OpenCSD version 1.4, on ARM64 systems.
      
         - Fix command line auto-complete of CPU events on aarch64.
      
        Build:
      
         - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked,
           as several tests use tracepoints, those should be skipped.
      
         - More fallout fixes for the removal of tools/lib/traceevent/.
      
         - Fix build error when linking with libpfm"

      Pull tracing fix from Steven Rostedt:
       "Fix race that causes a warning of corrupt ring buffer
      
        With the change that allows to read the "trace" file without disabling
        writing to the ring buffer, there was an integrity check of the ring
        buffer in the iterator read code, that expected the ring buffer to be
        write disabled. This caused the integrity check to trigger when stress
        reading the "trace" file while writing was happening.
      
        The integrity check is a bit aggressive (and has never triggered in
        practice). Change it so that it checks just the integrity of the
        linked pages without clearing the flags inside the pointers. This
        removes the warning that was being triggered"
      
      [ Heh. This was supposed to have gone in last week before the 6.2
        release, but Steven forgot to actually add me to the participants of
        the pull request, so here it is, a week later   - Linus ]

       "Documentation updates.
      
        Add read-modify-write sequences, which means that stronger primitives
        more consistently result in stronger ordering, while still remaining
        in the envelope of the hardware that supports Linux.
      
        Address, data, and control dependencies used to ignore data that was
        stored in temporaries. This update extends these dependency chains to
        include unmarked intra-thread stores and loads. Note that these
        unmarked stores and loads should not be concurrently accessed from
        multiple threads, and doing so will cause LKMM to flag such accesses

      Pull cifs client updates from Steve French:
       "The largest subset of this is from David Howells et al: making the
        cifs/smb3 driver pass iov_iters down to the lowest layers, directly to
        the network transport rather than passing lists of pages around,
        helping multiple areas:
      
         - Pin user pages, thereby fixing the race between concurrent DIO read
           and fork, where the pages containing the DIO read buffer may end up
           belonging to the child process and not the parent - with the result
           that the parent might not see the retrieved data.
      
         - cifs shouldn't take refs on pages extracted from non-user-backed
           iterators (eg. KVEC). With these changes, cifs will apply the
           appropriate cleanup.
      
         - Making it easier to transition to using folios in cifs rather than
           pages by dealing with them through BVEC and XARRAY iterators.
      
         - Allowing cifs to use the new splice function
      
        The remainder are:
      
         - fixes for stable, including various fixes for uninitialized memory,
           wrong length field causing mount issue to very old servers,
           important directory lease fixes and reconnect fixes
      
         - cleanups (unused code removal, change one element array usage, and
           a change form strtobool to kstrtobool, and Kconfig cleanups)
      
         - SMBDIRECT (RDMA) fixes including iov_iter integration and UAF fixes
      
         - reconnect fixes
      
         - multichannel fixes, including improving channel allocation (to
           least used channel)

      Pull nfsd updates from Chuck Lever:
       "Two significant security enhancements are part of this release:
      
         - NFSD's RPC header encoding and decoding, including RPCSEC GSS and
           gssproxy header parsing, has been overhauled to make it more
           memory-safe.
      
         - Support for Kerberos AES-SHA2-based encryption types has been added
           for both the NFS client and server. This provides a clean path for
           deprecating and removing insecure encryption types based on DES and
           SHA-1. AES-SHA2 is also FIPS-140 compliant, so that NFS with
           Kerberos may now be used on systems with fips enabled.
      
        In addition to these, NFSD is now able to handle crossing into an
        auto-mounted mount point on an exported NFS mount. A number of fixes
        have been made to NFSD's server-side copy implementation.
      
        RPC metrics have been converted to per-CPU variables. This helps
        reduce unnecessary cross-CPU and cross-node memory bus traffic, and
        significantly reduces noise when KCSAN is enabled"

       - Reorganize zonefs code to split file related operations to a new

       - Modify zonefs to use dynamically allocated inodes and dentries (using
         the inode and dentry caches) instead of statically allocating
         everything on mount. This saves a significant amount of memory for
         very large zoned block devices with 10s of thousands of zones (me)
