Pull thread updates from Christian Brauner:
 "We have been discussing using pidfds to attach to namespaces for quite
  a while and the patches have in one form or another already existed
  for about a year. But I wanted to wait to see how the general api
  would be received and adopted.

  This contains the changes to make it possible to use pidfds to attach
  to the namespaces of a process, i.e. they can be passed as the first
  argument to the setns() syscall.

  When only a single namespace type is specified the semantics are
  equivalent to passing an nsfd. That means setns(nsfd, CLONE_NEWNET)
  equals setns(pidfd, CLONE_NEWNET).

  However, when a pidfd is passed, multiple namespace flags can be
  specified in the second setns() argument and setns() will attach the
  caller to all the specified namespaces all at once or to none of them.

  Specifying 0 is not valid together with a pidfd. Here are just two
  obvious examples:

    setns(pidfd, CLONE_NEWPID | CLONE_NEWNS | CLONE_NEWNET);
    setns(pidfd, CLONE_NEWUSER);

  Allowing to also attach subsets of namespaces supports various
  use-cases where callers setns to a subset of namespaces to retain
  privilege, perform an action and then re-attach another subset of
  namespaces.

  Apart from significantly reducing the number of syscalls needed to
  attach to all currently supported namespaces (eight "open+setns"
  sequences vs just a single "setns()"), this also allows atomic setns
  to a set of namespaces, i.e. either attaching to all namespaces
  succeeds or we fail without having changed anything.

  This is centered around a new internal struct nsset which holds all
  information necessary for a task to switch to a new set of namespaces
  atomically. Fwiw, with this change a pidfd becomes the only token
  needed to interact with a container. I'm expecting this to be
  picked-up by util-linux for nsenter rather soon.

  Associated with this change is a shiny new test-suite dedicated to
  setns() (for pidfds and nsfds alike)"

Pull btrfs updates from David Sterba:
 "Highlights:

   - speedup dead root detection during orphan cleanup, eg. when there
     are many deleted subvolumes waiting to be cleaned, the trees are
     now looked up in radix tree instead of a O(N^2) search

   - snapshot creation with inherited qgroup will mark the qgroup
     inconsistent, requires a rescan

   - send will emit file capabilities after chown, this produces a
     stream that does not need postprocessing to set the capabilities
     again

   - direct io ported to iomap infrastructure, cleaned up and simplified
     code, notably removing last use of struct buffer_head in btrfs code

  Core changes:

   - factor out backreference iteration, to be used by ordinary
     backreferences and relocation code

   - improved global block reserve utilization
      * better logic to serialize requests
      * increased maximum available for unlink
      * improved handling on large pages (64K)

   - direct io cleanups and fixes
      * simplify layering, where cloned bios were unnecessarily created
        for some cases
      * error handling fixes (submit, endio)
      * remove repair worker thread, used to avoid deadlocks during
        repair

   - refactored block group reading code, preparatory work for new type
     of block group storage that should improve mount time on large
     filesystems

  Cleanups:

   - cleaned up (and slightly sped up) set/get helpers for metadata data
     structure members

   - root bit REF_COWS got renamed to SHAREABLE to reflect the that the
     blocks of the tree get shared either among subvolumes or with the
     relocation trees

  Fixes:

   - when subvolume deletion fails due to ENOSPC, the filesystem is not
     turned read-only

   - device scan deals with devices from other filesystems that changed
     ownership due to overwrite (mkfs)

   - fix a race between scrub and block group removal/allocation

   - fix long standing bug of a runaway balance operation, printing the
     same line to the syslog, caused by a stale status bit on a reloc
     tree that prevented progress

   - fix corrupt log due to concurrent fsync of inodes with shared
     extents

Pull DAX updates part two from Darrick Wong:
 "This time around, we're hoisting the DONTCACHE flag from XFS into the
  VFS so that we can make the incore DAX mode changes become effective
  sooner.

  We can't change the file data access mode on a live inode because we
  don't have a safe way to change the file ops pointers. The incore
  state change becomes effective at inode loading time, which can happen
  if the inode is evicted. Therefore, we're making it so that
  filesystems can ask the VFS to evict the inode as soon as the last
  holder drops.

  The per-fs changes to make this call this will be in subsequent pull
  requests from Ted and myself.

  Summary:

   - Introduce DONTCACHE flags for dentries and inodes. This hint will
     cause the VFS to drop the associated objects immediately after the
     last put, so that we can change the file access mode (DAX or page
     cache) on the fly"

Pull DAX updates part one from Darrick Wong:
 "After many years of LKML-wrangling about how to enable programs to
  query and influence the file data access mode (DAX) when a filesystem
  resides on storage devices such as persistent memory, Ira Weiny has
  emerged with a proposed set of standard behaviors that has not been
  shot down by anyone! We're more or less standardizing on the current
  XFS behavior and adapting ext4 to do the same.

  This is the first of a handful pull requests that will make ext4 and
  XFS present a consistent interface for user programs that care about
  DAX. We add a statx attribute that programs can check to see if DAX is
  enabled on a particular file. Then, we update the DAX documentation to
  spell out the user-visible behaviors that filesystems will guarantee
  (until the next storage industry shakeup). The on-disk inode flag has
  been in XFS for a few years now.

  Summary:

   - Clean up io_is_direct.

   - Add a new statx flag to indicate when file data access is being
     done via DAX (as opposed to the page cache).

   - Update the documentation for how system administrators and
     application programmers can take advantage of the (still
     experimental DAX) feature"

Pull xfs updates from Darrick Wong:
 "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.

  Summary:

   - 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"

Pull SELinux updates from Paul Moore:
 "The highlights:

   - A number of improvements to various SELinux internal data
     structures to help improve performance. We move the role
     transitions into a hash table. In the content structure we shift
     from hashing the content string (aka SELinux label) to the
     structure itself, when it is valid. This last change not only
     offers a speedup, but it helps us simplify the code some as well.

   - Add a new SELinux policy version which allows for a more space
     efficient way of storing the filename transitions in the binary
     policy. Given the default Fedora SELinux policy with the unconfined
     module enabled, this change drops the policy size from ~7.6MB to
     ~3.3MB. The kernel policy load time dropped as well.

   - Some fixes to the error handling code in the policy parser to
     properly return error codes when things go wrong"

This reverts commit de058420.

There is no actual tipc_node refcnt leak as stated in the above commit.
The refcnt is hold carefully for the case of an asynchronous decryption
(i.e. -EINPROGRESS/-EBUSY and skb = NULL is returned), so that the node
object cannot be freed in the meantime. The counter will be re-balanced
when the operation's callback arrives with the decrypted buffer if any.
In other cases, e.g. a synchronous crypto the counter will be decreased
immediately when it is done.

Now with that commit, a kernel panic will occur when there is no node
found (i.e. n = NULL) in the 'tipc_rcv()' or a premature release of the
node object.

This commit solves the issues by reverting the said commit, but keeping
one valid case that the 'skb_linearize()' is failed.
