  * PROBLEM DESCRIPTION: HIGH IRLM CPU IN V530 EVEN              *
  *                      AFTER PI41106.                          *

  ****************************************************************
  PROBLEM SUMMARY:
  PI41106 was designed to reduce CPU utilization in IRLM address
  space by reducing lock status collection. However a code path
  that collected this information was unchanged.
  
  PROBLEM CONCLUSION:
  Code paths redesigned to reduce collection.
  
  KEYWORDS:
  IRLM CPU
  

Problem conclusion

• Code paths redesigned to reduce collection.
