-    # Class for profiling code on a per line basis.
-    #
-    # The LineProfiler class can be used to profile code on per line basis
-    # without littering your code with Ruby implementation specific profiling
-    # methods.
-    #
-    # This profiler only includes samples taking longer than a given threshold
-    # and those that occur in the actual application (e.g. files from Gems are
-    # ignored).
-    class LineProfiler
-      # The minimum amount of time that has to be spent in a file for it to be
-      # included in a list of samples.
-      MINIMUM_DURATION = 10.0
-
-      # Profiles the given block.
-      #
-      # Example:
-      #
-      #     profiler = LineProfiler.new
-      #
-      #     retval, samples = profiler.profile do
-      #       "cats are amazing"
-      #     end
-      #
-      #     retval  # => "cats are amazing"
-      #     samples # => [#<Gitlab::Sherlock::FileSample ...>, ...]
-      #
-      # Returns an Array containing the block's return value and an Array of
-      # FileSample objects.
