       "There is a long-standing subtle destroy_workqueue() bug where a
        workqueue can be destroyed while internal work items used for flushing

      Pull device mapper updates from Mike Snitzer:
      
       - Add DM infrastructure for IMA-based remote attestion. These changes
         are the basis for deploying DM-based storage in a "cloud" that must
         validate configurations end-users run to maintain trust. These DM
         changes allow supported DM targets' configurations to be measured via
         IMA. But the policy and enforcement (of which configurations are
         valid) is managed by something outside the kernel (e.g. Keylime).
      
       - Fix DM crypt scalability regression on systems with many cpus due to
         percpu_counter spinlock contention in crypt_page_alloc().
      
       - Use in_hardirq() instead of deprecated in_irq() in DM crypt.
      
       - Add event counters to DM writecache to allow users to further assess
         how the writecache is performing.
      
       - Various code cleanup in DM writecache's main IO mapping function.

        While this required the addition of a (simple) new vfs helper all the

        can trust the maintainer and the btrfs folks were really fast and
        helpful in reviewing this work.
      
        As always, associated with the btrfs port for idmapped mounts is a new
        fstests extension specifically concerned with btrfs ioctls (e.g.
        subvolume creation, deletion etc.) on idmapped mounts which can be

       "This is a cleanup for close_range() which was sent as part of a bugfix
        we did some time ago in commit 9b5b8722 ("file: fix close_range()
        for unshare+cloexec").
      
        We used to share more code between some helpers for close_range()
        which made retrieving the maximum number of open fds before calling
        into the helpers sensible. But with the introduction of
        CLOSE_RANGE_CLOEXEC and the need to retrieve the number of maximum fds
        once more for CLOSE_RANGE_CLOEXEC that stopped making sense. So the
        code was in a dumb in-limbo state.
      
        Fix this by simplifying the code a bit.
      
        The original idea was to only fix the bug itself and make backporting
        easy. And since the cleanup wasn't very pressing I left it in
        linux-next for a very long time. I didn't pull the patches from the

        The use-case comes from the criu folks which have been struggling with

        have been discussed at Plumbers before, e.g.
      
            https://www.linuxplumbersconf.org/event/7/contributions/640/
      
        The extension to move_mount() enables criu to restore any set of mount
        namespaces, mount trees and sharing group trees without introducing
        yet more complexity into mount propagation itself.

      Pull iomap updates from Darrick Wong:
       "The most notable externally visible change for this cycle is the
        addition of support for reads to inline tail fragments of files, which
        was requested by the erofs developers; and a correction for a kernel
        memory corruption bug if the sysadmin tries to activate a swapfile
        with more pages than the swapfile header suggests.
      
        We also now report writeback completion errors to the file mapping
        correctly, instead of munging all errors into EIO.
      
        Internally, the bulk of the changes are Christoph's patchset to reduce
        the indirect function call count by a third to a half by converting
        iomap iteration from a loop pattern to a generator/consumer pattern.
        As an added bonus, fsdax no longer open-codes iomap apply loops.
      
        Summary:
      
         - Simplify the bio_end_page usage in the buffered IO code.
      
         - Support reading inline data at nonzero offsets for erofs.
      
         - Fix some typos and bad grammar.
      
         - Convert kmap_atomic usage in the inline data read path.
      
         - Add some extra inline data input checking.
      
         - Fix a memory corruption bug stemming from iomap_swapfile_activate
           trying to activate more pages than mm was expecting.
      
         - Pass errnos through the page writeback code so that writeback
           errors are reported correctly instead of being munged to EIO.
      
         - Replace iomap_apply with a open-coded iterator loops to reduce the
           number of indirect calls by a third to a half.
      
         - Refactor the fsdax code to use iomap iterators instead of the

      Pull btrfs updates from David Sterba:
       "The highlights of this round are integrations with fs-verity and
        idmapped mounts, the rest is usual mix of minor improvements, speedups
        and cleanups.
      
        There are some patches outside of btrfs, namely updating some VFS
        interfaces, all straightforward and acked.
      
        Features:
      
         - fs-verity support, using standard ioctls, backward compatible with
           read-only limitation on inodes with previously enabled fs-verity
      
         - idmapped mount support
      
         - make mount with rescue=ibadroots more tolerant to partially damaged
           trees
      
         - allow raid0 on a single device and raid10 on two devices,
           degenerate cases but might be useful as an intermediate step during
           conversion to other profiles
      
         - zoned mode block group auto reclaim can be disabled via sysfs knob
      
        Performance improvements:
      
         - continue readahead of node siblings even if target node is in
           memory, could speed up full send (on sample test +11%)
      
         - batching of delayed items can speed up creating many files
      
         - fsync/tree-log speedups
             - avoid unnecessary work (gains +2% throughput, -2% run time on
               sample load)
             - reduced lock contention on renames (on dbench +4% throughput,
               up to -30% latency)
      
        Fixes:
      
         - various zoned mode fixes
      
         - preemptive flushing threshold tuning, avoid excessive work on
           almost full filesystems
      
        Core:
      
         - continued subpage support, preparation for implementing remaining
           features like compression and defragmentation; with some
           limitations, write is now enabled on 64K page systems with 4K
           sectors, still considered experimental
             - no readahead on compressed reads
             - inline extents disabled
             - disabled raid56 profile conversion and mount
      
         - improved flushing logic, fixing early ENOSPC on some workloads
      
         - inode flags have been internally split to read-only and read-write
           incompat bit parts, used by fs-verity
      
         - new tree items for fs-verity
             - descriptor item
             - Merkle tree item
      
         - inode operations extended to be namespace-aware
      
         - cleanups and refactoring
      
        Generic code changes:
      
         - fs: new export filemap_fdatawrite_wbc
      
         - fs: removed sync_inode
      
         - block: bio_trim argument type fixups

      Pull initial ksmbd implementation from Steve French:
       "Initial merge of kernel smb3 file server, ksmbd.
      
        The SMB family of protocols is the most widely deployed network
        filesystem protocol, the default on Windows and Macs (and even on many
        phones and tablets), with clients and servers on all major operating
        systems, but lacked a kernel server for Linux. For many cases the
        current userspace server choices were suboptimal either due to memory
        footprint, performance or difficulty integrating well with advanced
        Linux features.
      
        ksmbd is a new kernel module which implements the server-side of the
        SMB3 protocol. The target is to provide optimized performance, GPLv2
        SMB server, and better lease handling (distributed caching). The
        bigger goal is to add new features more rapidly (e.g. RDMA aka
        "smbdirect", and recent encryption and signing improvements to the
        protocol) which are easier to develop on a smaller, more tightly
        optimized kernel server than for example in Samba.
      
        The Samba project is much broader in scope (tools, security services,
        LDAP, Active Directory Domain Controller, and a cross platform file
        server for a wider variety of purposes) but the user space file server
        portion of Samba has proved hard to optimize for some Linux workloads,
        including for smaller devices.
      
        This is not meant to replace Samba, but rather be an extension to
        allow better optimizing for Linux, and will continue to integrate well
        with Samba user space tools and libraries where appropriate. Working
        with the Samba team we have already made sure that the configuration
        files and xattrs are in a compatible format between the kernel and
        user space server.
      
        Various types of functional and regression tests are regularly run
        against it. One example is the automated 'buildbot' regression tests
        which use the Linux client to test against ksmbd, e.g.
      
           http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/8/builds/56
      
        but other test suites, including Samba's smbtorture functional test
        suite are also used regularly"
