Sorry Linus, I totally FUBARed the addressing on the pull request.
Resending directly to you so that it doesn't get lost in the spam
folder.

Hi Linus,

Please pull the new XFS code for 5.8.  Most of the changes this cycle
are refactoring of existing code in preparation for things landing in
the future.  We also fixed various problems and deficiencies in the
quota implementation, and (I hope) the last of the stale read vectors by
forcing write allocations to go through the unwritten state until the
write completes.

This branch merges cleanly with master as of a few minutes ago, so
please let me know if anything strange happens.  I anticipate a second
pull request next week for a DAX-related restructuring that requires the
DAX branch (sent separately).

  xfs: more lockdep whackamole with kmem_alloc* (2020-05-27 08:49:28 -0700)

----------------------------------------------------------------
New code for 5.8:
    - Various cleanups to remove dead code, unnecessary conditionals,
      asserts, etc.
    - Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
      redundantly.
    - Tighten up our dmesg logging to ensure that everything is prefixed
      with 'XFS' for easier grepping.
    - Kill a bunch of typedefs.
    - Refactor the deferred ops code to reduce indirect function calls.
    - Increase type-safety with the deferred ops code.
    - Make the DAX mount options a tri-state.
    - Fix some error handling problems in the inode flush code and clean up
      other inode flush warts.
    - Refactor log recovery so that each log item recovery functions now live
      with the other log item processing code.
    - Fix some SPDX forms.
    - Fix quota counter corruption if the fs crashes after running
      quotacheck but before any dquots get logged.
    - Don't fail metadata verification on zero-entry attr leaf blocks, since
      they're just part of the disk format now due to a historic lack of log
      atomicity.
    - Don't allow SWAPEXT between files with different [ugp]id when quotas
      are enabled.
    - Refactor inode fork reading and verification to run directly from the
      inode-from-disk function.  This means that we now actually guarantee
      that _iget'ted inodes are totally verified and ready to go.
    - Move the incore inode fork format and extent counts to the ifork
      structure.
    - Scalability improvements by reducing cacheline pingponging in
      struct xfs_mount.
    - More scalability improvements by removing m_active_trans from the
      hot path.
    - Fix inode counter update sanity checking to run /only/ on debug
      kernels.
    - Fix longstanding inconsistency in what error code we return when a
      program hits project quota limits (ENOSPC).
    - Fix group quota returning the wrong error code when a program hits
      group quota limits.
    - Fix per-type quota limits and grace periods for group and project
      quotas so that they actually work.
    - Allow extension of individual grace periods.
    - Refactor the non-reclaim inode radix tree walking code to remove a
      bunch of stupid little functions and straighten out the
      inconsistent naming schemes.
    - Fix a bug in speculative preallocation where we measured a new
      allocation based on the last extent mapping in the file instead of
      looking farther for the last contiguous space allocation.
    - Force delalloc writes to unwritten extents.  This closes a
      stale disk contents exposure vector if the system goes down before
      the write completes.
    - More lockdep whackamole.
