Yes. copy below - just indented same text

  -"num_closids":  The number of CLOSIDs which are valid for this
  -            resource. The kernel uses the smallest number of
  -            CLOSIDs of all enabled resources as limit.
  +"num_closids":      The number of CLOSIDs which are valid for this
  +                    resource. The kernel uses the smallest number of
  +                    CLOSIDs of all enabled resources as limit.
