        There are some (minor) user-visible changes:
         - We no longer deny write access to shared libaries loaded via legacy
           uselib(); this behavior matches modern user space e.g. dlopen().
         - We no longer deny write access to the elf interpreter after exec
           completed, treating it just like shared libraries (which it often
         - We always deny write access to the file linked via /proc/pid/exe:
           sys_prctl(PR_SET_MM_MAP/EXE_FILE) will fail if write access to the
           file cannot be denied, and write access to the file will remain
           denied until the link is effectivel gone (exec, termination,
           sys_prctl(PR_SET_MM_MAP/EXE_FILE)) -- just as if exec'ing the file.
        Cross-compiled for a bunch of architectures (alpha, microblaze, i386,
        s390x, ...) and verified via ltp that especially the relevant tests
        (i.e., creat07 and execve04) continue working as expected"

      Merge NTFSv3 filesystem from Konstantin Komarov:
       "This patch adds NTFS Read-Write driver to fs/ntfs3.
        Having decades of expertise in commercial file systems development and
        huge test coverage, we at Paragon Software GmbH want to make our
        contribution to the Open Source Community by providing implementation
        of NTFS Read-Write driver for the Linux Kernel.
        This is fully functional NTFS Read-Write driver. Current version works
        with NTFS (including v3.1) and normal/compressed/sparse files and
        supports journal replaying.
        We plan to support this version after the codebase once merged, and
        add new features and fix bugs. For example, full journaling support
        over JBD will be added in later updates"

      Pull f2fs updates from Jaegeuk Kim:
       "In this cycle, we've addressed some performance issues such as lock
        contention, misbehaving compress_cache, allowing extent_cache for
        compressed files, and new sysfs to adjust ra_size for fadvise.
        In order to diagnose the performance issues quickly, we also added an
        iostat which shows the IO latencies periodically.
        On the stability side, we've found two memory leakage cases in the
        error path in compression flow. And, we've also fixed various corner
        cases in fiemap, quota, checkpoint=disable, zstd, and so on.
         - avoid long checkpoint latency by releasing nat_tree_lock
         - collect and show iostats periodically
         - support extent_cache for compressed files
         - add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL)
         - report f2fs GC status via sysfs
         - add discard_unit=%s in mount option to handle zoned device
        Bug fixes:
         - fix two memory leakages when an error happens in the compressed IO flow
         - fix commpress_cache to get the right LBA
         - fix fiemap to deal with compressed case correctly
         - fix wrong EIO returns due to SBI_NEED_FSCK
         - fix missing writes when enabling checkpoint back
         - fix quota deadlock
         - fix zstd level mount option
        In addition to the above major updates, we've cleaned up several code
        paths such as dio, unnecessary operations, debugfs/f2fs/status, sanity
        check, and typos"
