While trawling through the dedupe file comparison code trying to fix
page deadlocking problems, Dave Chinner noticed that the reflink code
only takes shared IOLOCK/MMAPLOCKs on the source file.  Because
page_mkwrite and directio writes do not take the EXCL versions of those
locks, this means that reflink can race with writer processes.

For pure remapping this can lead to undefined behavior and file
corruption; for dedupe this means that we cannot be sure that the
contents are identical when we decide to go ahead with the remapping.

When dedupe wants to use the page cache to compare parts of two files
for dedupe, we must be very careful to handle locking correctly.  The
current code doesn't do this.  It must lock and unlock the page only
once if the two pages are the same, since the overlapping range check
doesn't catch this when blocksize < pagesize.  If the pages are distinct
but from the same file, we must observe page locking order and lock them
in order of increasing offset to avoid clashing with writeback locking.

Pull libnvdimm fixes from Dan Williams:
 "A collection of locking and async operations fixes for v5.3-rc2. These
  had been soaking in a branch targeting the merge window, but missed
  due to a regression hunt. This fixed up version has otherwise been in
  -next this past week with no reported issues.

  In order to gain confidence in the locking changes the pull also
  includes a debug / instrumentation patch to enable lockdep coverage
  for libnvdimm subsystem operations that depend on the device_lock for
  exclusion. As mentioned in the changelog it is a hack, but it works
  and documents the locking expectations of the sub-system in a way that
  others can use lockdep to verify. The driver core touches got an ack
  from Greg.

  Summary:

   - Fix duplicate device_unregister() calls (multiple threads competing
     to do unregister work when scheduling device removal from a sysfs
     attribute of the self-same device).

   - Fix badblocks registration order bug. Ensure region badblocks are
     initialized in advance of namespace registration.

   - Fix a deadlock between the bus lock and probe operations.

   - Export device-core infrastructure to coordinate async operations
     via the device ->dead state.

   - Add device-core infrastructure to validate device_lock() usage with
     lockdep"

Pull drm fixes from Daniel Vetter:
 "Dave seems to collect an entire streak of things happening, so again
  me typing pull summary.

  Nothing nefarious here, most of the fixes are for new stuff or things
  users won't see. The amd-display patches are a bit different, and very
  much look like they should have at least some cc: stable tags. Might
  be amd is a bit too comfortable with their internal tree and not
  enough looking at upstream. Dave&me are looking into this, in case
  something needs rectified with process here.

  Also no intel fixes pull, but intel CI is general become rather good,
  still I guess expect a notch more for -rc3.

  Summary:

  amdgpu:
   - fixes for (new in 5.3) hw support (vega20, navi)
   - disable RAS
   - lots of display fixes all over (audio, DSC, dongle, clock mgr)

  ttm:
   - fix dma_free_attrs calls to appease dma debugging

  msm:
   - fixes for dma-api, locking debug and compiler splats

  core:
   - fix cmdline mode to not apply rotation if not specified (new in 5.3)
   - compiler warn fix"

We should only set the max segment size to unlimited if we actually
have a virt boundary.  Otherwise we accidentally clear that limit
when called from the SCSI midlayer, which always calls
blk_queue_virt_boundary, even if that mask is 0.
