      Pull more USB updates from Greg KH:
 "Here are some straggler USB-serial changes for 5.15-rc1.

  These were not included in the first pull request as they came in
  "late" from Johan and I had missed them in my pull request earlier
  this week.

  Nothing big in here, just some USB to serial driver updates and fixes.
  All of these were in linux-next before I pulled them into my tree, and
  have been in linux-next all this week from my tree with no reported
  problems"

      Linus Torvalds authored 
      Pull MAP_DENYWRITE removal from David Hildenbrand:
 "Remove all in-tree usage of MAP_DENYWRITE from the kernel and remove
  VM_DENYWRITE.

  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
     is).

   - 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"

      Merge tag 'f2fs-for-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs · 6abaa83c
      Linus Torvalds authored 
      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.

  Enhancements:
   - 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"
