      Pull btrfs fixes from David Sterba:
       "Several xes and one old ioctl deprecation. Namely there's fix for
        crashes/warnings with lzo compression that was suspected to be caused
        by first pull merge resolution, but it was a different bug.
      
        Summary:
      
         - regression fix for a crash in lzo due to missing boundary checks of
           the page array
      
         - fix crashes on ARM64 due to missing barriers when synchronizing
           status bits between work queues
      
         - silence lockdep when reading chunk tree during mount
      
         - fix false positive warning in integrity checker on devices with
           disabled write caching
      
         - fix signedness of bitfields in scrub
      
         - start deprecation of balance v1 ioctl"

      Linus Torvalds authored
      Pull setattr idmapping fix from Christian Brauner:
       "This contains a simple fix for setattr. When determining the validity
        of the attributes the ia_{g,u}id fields contain the value that will be
        written to inode->i_{g,u}id. When the {g,u}id attribute of the file
        isn't altered and the caller's fs{g,u}id matches the current {g,u}id
        attribute the attribute change is allowed.
      
        The value in ia_{g,u}id does already account for idmapped mounts and
        will have taken the relevant idmapping into account. So in order to
        verify that the {g,u}id attribute isn't changed we simple need to
        compare the ia_{g,u}id value against the inode's i_{g,u}id value.
      
        This only has any meaning for idmapped mounts as idmapping helpers are
        idempotent without them. And for idmapped mounts this really only has
        a meaning when circular idmappings are used, i.e. mappings where e.g.
        id 1000 is mapped to id 1001 and id 1001 is mapped to id 1000. Such
        ciruclar mappings can e.g. be useful when sharing the same home
        directory between multiple users at the same time.
      
        Before this patch we could end up denying legitimate attribute changes
        and allowing invalid attribute changes when circular mappings are
        used. To even get into this situation the caller must've been
        privileged both to create that mapping and to create that idmapped
        mount.
      
        This hasn't been seen in the wild anywhere but came up when expanding
        the fstest suite during work on a series of hardening patches. All
        idmapped fstests pass without any regressions and we're adding new
        tests to verify the behavior of circular mappings.
      
        The new tests can be found at [1]"
