Merge tag 'vfs-5.8-merge-3' of git://git./fs/xfs/xfs-linux

Pull DAX updates part three from Darrick Wong:
 "Now that the xfs changes have landed, this third piece changes the
  FS_XFLAG_DAX ioctl code in xfs to request that the inode be reloaded
  after the last program closes the file, if doing so would make a S_DAX
  change happen. The goal here is to make dax access mode switching
  quicker when possible.

  Summary:

   - Teach XFS to ask the VFS to drop an inode if the administrator
     changes the FS_XFLAG_DAX inode flag such that the S_DAX state would
     change. This can result in files changing access modes without
     requiring an unmount cycle"
