      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"

      block: fix max segment size handling in blk_queue_virt_boundary · c6c84f78
      Christoph Hellwig authored
      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.

      fix the struct mount leak in umount_tree() · 19a1c409
      Al Viro authored
      	We need to drop everything we remove from the tree, whether
      mnt_has_parent() is true or not.  Usually the bug manifests as a slow
      memory leak (leaked struct mount for initramfs); it becomes much more
      visible in mount_subtree() users, such as btrfs.  There we leak
      a struct mount for btrfs superblock being mounted, which prevents
      fs shutdown on subsequent umount.

      btrfs: fix extent_state leak in btrfs_lock_and_flush_ordered_range · a3b46b86
      Naohiro Aota authored
      btrfs_lock_and_flush_ordered_range() loads given "*cached_state" into
      cachedp, which, in general, is NULL. Then, lock_extent_bits() updates
      "cachedp", but it never goes backs to the caller. Thus the caller still
      see its "cached_state" to be NULL and never free the state allocated
      under btrfs_lock_and_flush_ordered_range(). As a result, we will
      see massive state leak with e.g. fstests btrfs/005. Fix this bug by
      properly handling the pointers.

      ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips · 2756d914
      Takashi Iwai authored
      It turned out that the recent Intel HD-audio controller chips show a
      significant stall during the system PM resume intermittently.  It
      doesn't happen so often and usually it may read back successfully
      after one or more seconds, but in some rare worst cases the driver
      went into fallback mode.
      
      After trial-and-error, we found out that the communication stall seems
      covered by issuing the sync after each verb write, as already done for
      AMD and other chipsets.  So this patch enables the write-sync flag for
      the recent Intel chips, Skylake and onward, as a workaround.
      
      Also, since Broxton and co have the very same driver flags as Skylake,
      refer to the Skylake driver flags instead of defining the same
      contents again for simplification.

      access: avoid the RCU grace period for the temporary subjective credentials · d7852fbd
      Linus Torvalds authored
      
      
      It turns out that 'access()' (and 'faccessat()') can cause a lot of RCU
      work because it installs a temporary credential that gets allocated and
      freed for each system call.
      
      The allocation and freeing overhead is mostly benign, but because
      credentials can be accessed under the RCU read lock, the freeing
      involves a RCU grace period.
      
      Which is not a huge deal normally, but if you have a lot of access()
      calls, this causes a fair amount of seconday damage: instead of having a
      nice alloc/free patterns that hits in hot per-CPU slab caches, you have
      all those delayed free's, and on big machines with hundreds of cores,
      the RCU overhead can end up being enormous.
      
      But it turns out that all of this is entirely unnecessary.  Exactly
      because access() only installs the credential as the thread-local
      subjective credential, the temporary cred pointer doesn't actually need
      to be RCU free'd at all.  Once we're done using it, we can just free it
      synchronously and avoid all the RCU overhead.
      
      So add a 'non_rcu' flag to 'struct cred', which can be set by users that
      know they only use it in non-RCU context (there are other potential
      users for this).  We can make it a union with the rcu freeing list head
      that we need for the RCU case, so this doesn't need any extra storage.
      
      Note that this also makes 'get_current_cred()' clear the new non_rcu
      flag, in case we have filesystems that take a long-term reference to the
      cred and then expect the RCU delayed freeing afterwards.  It's not
      entirely clear that this is required, but it makes for clear semantics:
      the subjective cred remains non-RCU as long as you only access it
      synchronously using the thread-local accessors, but you _can_ use it as
      a generic cred if you want to.
      
      It is possible that we should just remove the whole RCU markings for
      ->cred entirely.  Only ->real_cred is really supposed to be accessed
      through RCU, and the long-term cred copies that nfs uses might want to
      explicitly re-enable RCU freeing if required, rather than have
      get_current_cred() do it implicitly.
      
      But this is a "minimal semantic changes" change for the immediate
      problem.
